A television is on in a dark and empty room…

"Preliminary reports have as many as 500 people feared dead in the collapse of a 20 story apartment building in Manhattan earlier this afternoon. Among those feared killed are at least 30 firefighters and rescue personnel."

The channel changes

"The scene brings back eerie reminders of September 11, 2001. There are at least 500 people feared dead in this Manhattan Apartment building collapse. Another blow to the FDNY and NYPD as there are as many as 50 members still unaccounted for at this hour."

The television is turned off.

EARLIER IN THE DAY

"So you ready for a vacation yet?" DK teases Walsh about Aaron's upcoming 2nd birthday party.

"Nah, it's not so bad." Walsh replies

"Yeah, it gets easier as they get older." Jimmy reassures Walsh

"He's a good kid, just into everything." Walsh smiles

"Just like his old man then." Logan cracks

"I think he gets it from his mother." Walsh returns

Taylor walks into the room.

"Nope, it's all you buddy." She kids

"Are we ever gonna get a call today?" Prescott asks

"Relax Prescott, for once in your life enjoy a little down time." DK comments

The alarm sounds.

"Adam 55-3 respond for chest pains 509 Morningside"

"The medics get to go out and we still gotta sit here." Prescott comments.

"Take it easy man, it's a break that we seldom get." Jimmy says

"So what are your plans for this weekend?" Bosco asks

"Well Fred and I are thinking about taking Emily and Charlie down to Hershey Park. It's supposed to be a nice weekend." Faith replies

"That sounds like a good idea. Get some relaxation, away from the city." Bosco comments

"What are your plans?" Faith asks

"I'm gonna work on my car, haven't had much time to do much of anything with it recently, so I'm gonna work on it." Bosco replies

"Sounds like a good plan for you." Faith says

"Does it bother you that we're still under a threat level of orange?" Bosco asks

"Yeah, I mean after 9-11 any threat level bothers me." Faith replies

"Yeah, I just get this feeling that something's gonna happen again, and we're gonna be powerless against it." Bosco adds

"Bos, we're never powerless against anything unless we fail to act." Faith replies.

Doc and Nicole arrive on the scene of an elderly man clutching his chest.

"Sir, we're Paramedics, did you call 911?" Doc asks

"Yes! My chest, it feels like someone's trying to crush it." The man replies

Nicole begins a work up on the man.

"Sir, do you have a history of an irregular heartbeat?" Nicole asks

"No." The man replies

Doc checks the man's heartbeat.

"It's definitely irregular." Doc replies

"Sir, have you ever had a heart condition before?" Nicole asks

"No." The man replies

"Okay, I need you to open your mouth and hold your tongue up so that I can spray this medicine in to help you get some relief from your pain." Nicole says

The man does as he's told and Nicole sprays the nitroglycerine under the man's tongue. They put the man on a gurney and prepare for transport.

Sully and Davis are on foot on 97th. They are ticketing cars that are illegally parked.

"It's a great day out here you know that?" Sully asks

"Yeah, kind of makes me forget that I am out here ticketing cars instead of driving around in the RMP." Davis replies

"I don't mind ticketing in this kind of weather." Sully comments

"Neither do I man, neither do I." Davis says noticing a couple young women up the street.

Sully looks and laughs.

"What?" Davis asks

"They're out of your league." Sully responds

"But I can still look can't I?" Davis asks with a laugh

Kim and Carlos are restocking the bus after a run.

"So any big plans this weekend?" Carlos asks

"Jimmy and I are taking Joey to the zoo." Kim replies

"That sounds like fun." Carlos replies

"What about you?" Kim asks

"I'm going to spend the day with Kylie tomorrow. Don't know what we're going to do yet, but it'll be a Daddy/Daughter day, you know?" Carlos replies

"That's so sweet Carlos. I hope that you have fun." Kim replies

"Yeah, hopefully the rain will hold off to make it better." Carlos says

Kim looks to the sky. "Yeah, I hope so too. It's too nice a weekend to rain."

"Yeah, especially when we get the whole thing off." Carlos replies.

"Exactly." Kim adds.

Gusler and Sasha are on foot on Lexington.

"So how long are you gonna walk without saying anything?" Sahsa asks

"Oh, sorry, I was just thinking." Gusler says

"Anything in particular?" Sasha asks

"Not really. The weather, art, things like that." Gusler responds

"I forgot you were into art." Sasha replies

"I love it. I think I may transfer to do the sketch art, you know, transfer off the streets." Gusler says

"You'd leave nice weather like this, easy days to do sketches?" Sasha asks

"Yeah. I love to draw." Gusler replies

"Okay, you really freak me out sometimes you know that Steven?" Sasha laughs

"Yeah." Gusler smiles.

Sargent Cruz sits at her desk doing paperwork. She had a drug bust and she's writing up the dealers.

"When am I gonna get out of here?" The one asks

"Whenever the judge says that you're free to go. And hopefully that's not going to be for a long time." Cruz snaps

"You're a real bitch you know that?" the dealer asks

"I've been called worse." Cruz replies

"I'll bet you have." The dealer replies

"I have one suggestion for you and that's to shut your mouth." Cruz snaps

"Yes ma'am." The dealer replies sarcastically as Cruz just looks at him.

People mill around an apartment building. Some enter, some exit. Some carry packages. Bosco and Faith are driving down 2nd Avenue. They decide to stop and get something to eat.

"What do you think?" Faith asks

"What do I think what?" Bosco asks

"Hotdog or Pizza?" Faith asks

"Hotdog." Bosco responds as he walks up to the vendor. "2 hotdogs everything on it and a water."

"And you ma'am?" The vendor asks

"I'll take 2 hotdogs, mustard and relish. And a ginger ale." Faith says

"That'll be 6.00" The vendor says

Bosco hands him the money as the vendor hands the two officers their food. They walk back towards the RMP to eat.

"Thanks Bos." Faith says

"No problem." He smiles as he takes a bite of his hotdog.

A few bites into their hotdogs a loud explosion is heard. Debris falls around the building where the explosion occurred.

"What was that?" Bosco yells dropping his food.

"That apartment building." Faith says pointing towards a building where flames shoot through some windows.

"5-5 David to central we need fire at 1505 2nd Ave. for an explosion." Bosco radios as he and Faith jump into the RMP and head towards the building.

My Sacrifice by Creed plays

The squad is sitting around the lounge when the call comes across.

"Squad 55, Ladder 100, Adam 55-3, Boy 55-3, explosion Residential building 1505 2nd Ave." The alarm cries

"Let's go boys!" Taylor yells as she jumps up from her chair.

They slide down the pole to get to their gear and the Engine. Lieutenant Johnson climbs into the cab. He looks at Walsh in the driver's seat.

"Let's go." Lieu says.

Gusler and Sasha are in the RMP and heading towards Bosco and Faith's location to assist with crowd control. Davis and Sully who are further away do the same.

Bosco looks at the building. "How many you think are still inside?" he yells to Faith

"I don't know." She replies.

"Come on, we gotta help get them out of there!" Bosco says heading into the building

"Bos, we're not equipped for this!" Faith says

"People are going to die if they don't get out." Bosco replies

Faith follows Bosco into the building as smoke continues to rise from the windows.

People are screaming and smoke billows through the stairwells. People make their way down, streaming through the smoke.

"Police, move to the right and continue down the stairs!" Bosco yells to the frightened people.

Sasha and Gusler arrive on the scene and they assist people coming out of the building.

"Keep moving people. Move away from the building!" Sasha yells

"Where are Bosco and Faith?" Gusler asks

"I guess they're inside." Sasha says

"Should we go in after them?" Gusler asks

"Yeah, let's go." Sasha replies as the pair enters the building.

"Bosco! Faith!" Sasha yells trying to locate her fellow officers.

Helicopters fly over the scene as fire engines start arriving on scene. Sully and Davis pull up as do Lieutenant Swersky and Sargent Cruz.

"Lieu, 55 David, 55 Edward are inside." Sully says

"What are they doing inside?" Swersky asks

The squad pulls onto the scene.

"Johnson, we got four officers inside." Swersky says

"Come on Bosco, the fire departments got to be here by now." Gusler urges clearly nervous to the surroundings

"Hang on." Bosco says

"Come on." Gusler urges again.

"What the hell do you got officers in there for?" Johnson asks

"They must have gone in right after it happened." Swersky replies

"Taylor, Prescott, Logan, there's four cops in there. Get them out." Johnson instructs

"Where are they?" Taylor asks

Sully looks at him. "I can't reach them on the radio. I don't know."

"Great, we're looking for four lost cops." Logan says sarcastically

"Walsh, operate the pumps, DK, Doherty help get that roof vented!" Johnson says, "And be safe!" he calls to his Squad

"Taylor, be careful!" Walsh says

"Always." She smiles

"I love you!" Walsh calls out

"I love you too." She replies before heading into the building.

"Bosco, we're supposed to be going down, not up!" Sasha says

"I hear something up there." Bosco replies heading up the stairs

"Come on, let's get out of here." Faith urges

"You guys go, there's something up here." Bosco insists and heads up. The other four officers follow.

Heading up the stairs the firefighters call out for the police.

"Bosco! Faith! Gusler! Monroe!" Taylor yells

"I can't believe we're searching for cops." Prescott says

Taylor, Prescott, and Logan enter the tenth floor hallway. There are heavy flames and they immediately set to battling the blaze. They enter an apartment to check for trapped occupants and find none. Then they continue down the hallway.

"Bosco we need to get out of here." Faith says coughing in the heavy smoke of the twelve floor.

"Yeah, there have got to be firefighters here by now." Sasha relays

"Let's go." Bosco says as he starts back down the smoke and flame filled hallway for the stairwell.

Suddenly an updraft of flames cuts off their retreat. The floor collapses trapping them from their exit.

"Shit!" Bosco says falling away from the flames.

"We're trapped." Gusler says under his breath.

"What about the apartments, the fire escape?" Sasha asks trying to find a way out.

The cops look back down the hallway to the window.

"It's our only hope." Faith says as the cops immediately start towards it.

As the cops approach the window they pass an open apartment. Gunfire breaks through the smoke. The cops immediately return fire.

"What was that?" Prescott asks noticing the gunfire

"It sounds like gunfire." Taylor says

"Yeah it does." Logan says

"Taylor to command, we have gunfire in the building." Taylor radios

Lieutenants Johnson and Swersky look at each other.

"Are you sure it's gunfire?" Johnson asks

"Yeah Lieu, it's gunfire." Taylor replies

"Be careful!" Johnson radios.

"Sure thing Lieu." Taylor replies

Swersky and Cruz look at each other,

"They got the ones responsible." Cruz thinks to herself almost celebratory.

"Drop your weapon!" Bosco yells

"You lost." A foreign voice yells

"No, you lost!" Bosco yells back returning fire.

They come face to face for the first time ever. The man is holding a device in his hand.

"It is finished now." He smiles as he presses a button on the device.
