My Main Character(s?)

A curious teen sneaks into the shuttle and goes to the satellite, his presence unknown to the captain and crew. He eventually gets caught, and he has a bumpy start concerning his relationship with the shuttle crew, but eventually over time, he matures and learns about what's going on around him during the course of the film. The crew also learns a few things from him as well, and a lasting friendship is established.

For the romantic part, I also think we should put in a stowaway as well. It could be someone who starts off hating our hero, but eventually comes to understand and love him. So it could be that when the character sneaks into the shuttle, the girl will follow and try to stop him, but eventually gets trapped with him for most of the film.
