Synopsis
In school, Stan questions what Mr. Garrison is teaching. He asks why they can't be like normal kids and do stuff like field trips. Garrison answers that they are actually going on a field trip to the planetarium tomorrow.

At the planetarium, the kids watch a laser show involving stars, except for Cartman who spots the Cheesy Poofs van that is auditioning kids for the Cheesy Poofs advert. Cartman is successful and makes it to the next round.

In the planetarium, the laser show takes an unusual twist and begins to brainwash everyone. As they leave the class say they want to visit the planetarium again.

Next day, Cartman goes to his audition and makes it through to the finale and discovers he will be appearing on television.

At the planetarium, the kids are even more brainwashed, so much they all become volunteers there.

On the school bus, a crazed kid from the planetarium shows up. He has escaped from there and is sent to Nurse Gollum upon arrival at school.

In the nurse's office, Mr. Mackey tries a mind to mind technique which helps Mr. Mackey discover what's going on.

Stan, Kyle and Kenny realise something isn't right - kids don't volunteer for things. Stan and Kyle work the laser machine and see how it effects Kenny. They turn the hypnotisation dial to the highest point and it kills Kenny.

Stan and Kyle go to Officer Barbrady and ask him to arrest the owner of the planetarium. Barbrady is hypnotised by the laser machine and convinced he is Elvis Presley.

Cartman appears on TV but discovers that none of his friends watched it because they were at the planetarium.

Mr. Mackey shows up at the planetarium, himself and the boys are soon took to be hypnotised. As they watch the lasers Cartman bursts in. An angry Cartman smashes the laser device and swings it round straight into the planetarium owner's eyes. The man is killed on contact and everyone is restored to normal.
