A normal day in the CSI lab.

Everyone was working as usual, Hodges was doing Trace analyst stuff. Grissom was in his office looking at his new beetle. Sara was with Nick on a case involving a dead women found in her bath. Ecklie was with Brass in interrogation. Warrick was on holiday with his wife.

Greg was casually walking down the corridor and Grissom suddenly called out. He went into his office and sat down in the empty chair in front of Grissom. "Grissom whats up?" He asked.

"Nothing and what have you done with your hair?" Grissom asked confused.

"Nothing I just added a little blond you know get the ladies lookin', that's all!" He replied smirking.

"OK, so anyway I need you to get a piece of evidence that is going to be presented in court tomorrow, it's evidence log number 5-11."

"Is that all, why do I have to get it, Grissom?" Complained Greg.

"You have to get it because your the only one not doing anything so, Shoo!" Said Grissom flapping his arms toward Greg.

"Fine but can I chose my next homicide, please!" Pleaded Greg getting up.

"Yes, fine, go, go!" Grissom said shooing again.

With that Greg left with a boyish grin. He carried down the corridor. He entered the evidence vault and started searching for evidence log number 5-11. What he didn't realize was when he closed the door behind him and had walked off, there was a quiet click and a small thump behind the door.

"5-9, 5-10, 5-12, oh here it is 5-11 and Grissom obliviously meant me to get the whole box as there is more than ten pieces of evidence in this box." He murmured while sighing.

Greg slides the box of the shelf but not realizing how heavy it was and he started staggering round the room towards the door. He shifted the box further up his arm and reach out to the door, it didn't open he shakes it violently. Exhausted he put down the box and started to shouted. Nobody could hear him.

Meanwhile...

Everything was quiet and peaceful in the labs the machines were whirling and lab techs were talking many moments went past when SUDDENLY A TSUNAMI OF WATER RUSHED THROUGH THE LABS, EVERYONE RAN WHILE GLASS SHATTERED AND EQUIPMENT FLEW EVERYWHERE. The Crime Lab was immediately evacuated everyone was standing outside, some were shivering and others were crying.

"Grissom!" Called Ecklie. "Everyone is present except Greg Sanders do you know where he could be?"

"Oh no, I sent him to the evidence vault to collect some evidence for tomorrows court trial." Grissom replied suddenly panicking.

"Oh my we had better alert the fire brigade." Ecklie said putting his hand to his head.

Three men slowly entered the lab, it was in a terrible state, the ceiling was coming down and all the glass lab walls had been smashed. The men made there way towards the evidence vault, when they got there they realize someone had purposely locked the door with a padlock. They exited and found Ecklie, "Sir we have found the door leading to the evidence vault locked, from he outside."

"I don't care, just get him out he could be dying, get him out NOW!" Yelled Ecklie.

The men went back in with heavy equipment have when they finally snapped the padlock in half, a horrifying sight met them...
