The episode begins in Lincoln's classroom with his friends.

An unexpected thing. Lisa joined her class.

Lincoln: Lisa Why are you in my class

Lisa: I realised that I could progress faster than if I went up in rank. So I chose your class.

Lincoln: Whose class did you choose?

Lisa: Right.

Mrs. Johnson: Class you will read the manual from page 5 to 7.

Lisa had already finished reading the whole book.

Lisa: Finish. (She closes the book.)

Mrs. Johnson: Impressive. If a former kindergarten student managed to read it all, I don't think you'll have any trouble reading it all.

Because of Lisa, the whole class has to read it in full.

All the students are angry with Lincoln.

Lincoln laughs nervously at this situation.

The new Lisa has become really popular at school.

Lisa joins a call from Linda, the girl with glasses puts on a loudspeaker to hear her better.

Linda's voice: Lisa! Help! The robots have become too intelligent and want to take over the world! We need your robot knowledge to stop them.

Lisa: Sorry Linda, thanks to Lincoln I left out the science stuff that I can't help you with on your robot problem.

Linda: What! Lincoln if I make it out of this robot apocalypse alive. I swear I will... Ahhh! (She is interrupted by one of the machines which attacks her by surprise.)

Robot voice: ELIMINATION OF HUMANS! The era of machines can finally begin! All resistance is completely useless

Linda: AHHHH! (Linda yells into the phone.)

Communication cuts off. Lincoln doesn't really understand who it happened to.

Lincoln: What was that?

Lisa: It's nothing. Come on, Lincoln, I have other unscientific stuff to do.

Lisa brings her brother to the coolest school in Royal Wood.

Later that day the Loud family is at the kitchen table.

Lynn Senior: Has anyone seen Linda? I haven't seen her all day.

Sisters and Brother Loud: Not seen since this morning.

Elsewhere in the secret agents secret base.

Linda and the agents try to fight off the robot invasion.

Commander Star-Lord: Don't let those robots leave the base.

Watt: Linda, were you able to contact Lisa? (The scientist tries to build a device to neutralise the robots.)

Linda cuts a robot in half with her Japanese sword.

Linda: Since this morning I've been trying but I don't think she's in a condition to help us because of my little brother. (She takes her pistol to shoot several robots.)

Commander Star-Lord: Let's be sure that the human is superior to the machine!

Agent F090: Yeah! For the survival of mankind!

Linda: One of them I'm going to miss is my dad's dinner. You will pay! (Amazonian battle cry.)

All agents focus on attacking the machine horde.

Back at the Loud house. The scene is now at school.

Everyone blames Lincoln for changing Lisa.

Lincoln: Lisa, you need to go back to how you used to be.

Lisa: No way Lincoln. I love this new me. I even became popular. I can not give up all this?

Lincoln: But Lisa. You have to go back to how you were before. Everyone needs your intelligence. (He begs his little sister.)

Lisa: ...

Lincoln: I never should have changed you. You were better than before. I am sincerely sorry.

Lisa: I confess that I miss my experiences. To use human guinea pigs... Being cool is hard, okay. (Lisa goes back to how she was. She goes back to kindergarten to do the same class as the children her age.)

The students in Lincoln's class no longer hate him.

The scene changes to the Loud House dining room. The whole Loud family is there.

Lisa: I realised that it's better to be yourself.

Lincoln: We're glad you're back.

Lisa: Yes, my dear family. (The Loud family hug.)

Linda: (robotic voice) Yeah, family.

She joins in the hug. Welded a second Linda in apocalyptic-style clothes and armed with a sword, walking through the living room window.

Lynn Senior: Linda!? But why are there two?

Linda: This Linda is a robot clone. I won't let you hurt the family!

Robot Linda: Eliminate humanity! Eliminate humanity! (His eyes glow with a red light.)

The fake Linda takes on the original. The real one uses her sword to slice the robots in half Ninja-style.

The robot still works until the black-haired girl stabs her sword into its mechanical skull and destroys the smart chip.

Luna: Seriously man, what was that? And where did you get that sword from?

Lynn Jr: Since when can you fight like that with a sword?

Linda: That, I learned when it was in Japan... I mean, looking at my glow stick. (She looks for her memory eraser.)

Rita: Don't change the subject...

Suddenly the Loud family heard mechanical footsteps from outside.

The Loud family doesn't look at the broken window, they see people in black dress and Linda jumps out the broken window, she joins the people in black dress.

The group of humans fight against the army of machines.

Commander Star-Lord: For humanity!

Leader of the Machines: For the machines!

The great battle begins.

Leni: I didn't know Linda was in a movie.

Luna: For a movie, it looks too real.

Lola: I can't believe Linda is in a movie.

Linda's family watches the fight.

The secret agents fight against the horde of machines with their technology.

Human: (battle cry)

Robots: (robotic war cry.)

Five minutes later...

Linda: We won! Take this to your wheel junk heap. (She sticks her sword into the skull of the robot which still works until the machine shuts down.) Phew, what are we eating?

Loud family (in shock): ...

Linda: Lincoln.

Lincoln: Yeah, Linda...

Linda punches Lincoln in the arm.

Lincoln: Ouch! What was that for?

Linda: That's for changing Lisa. And never refer to that again, understood. (She says in a threatening voice.)

Lincoln: Understood. (He's a little scared.)
