A crew of ten astronauts has set out on a training mission. There are three trainees on board--Yellow, Lime, and Cyan--who will learn through experience and instruction to prepare for future missions. However, everything changes when a crew member turns up dead within the first week of the journey. It appears to be a suicide and is dismissed as such. Then a frantic message comes in from ground control. Someone isn't supposed to be on that ship. With this horrifying knowledge, the crewmates frantically try to figure out a way to survive and get back home with the impostor among them.
