A group of teenage wannabe astronauts enjoy a Summer at Space Camp and soon find that only by working as a team can they avert disaster when a sentient robot called Jinx grants the wish of young Max (an avid Star Wars fan) to go in to space.
He ensures that there is a mechanical error which means, during an engine test with the kids on board, the shuttle must be launched. At the controls are Kathryn (a serious academic and pilot), Kevin (who only went to Space Camp to get a car off his father), Rudy (who wants to open a fast food franchise in Space), Trish (who wants to make contact with extra terrestrials) and their instructor Andi (who feels threatened by up and coming Kathryn).
Between them, they must figure out how to safely return to Earth when they have limited oxygen and no contact with NASA. When Andi is injured, it's up to the kids to fly the shuttle and find a way home, as well as each learning about their personalities along the way.
