It was a week like any other for the students of brixter university. Lectures, exams, socialising, nothing out of the ordinary. Apart from in the science faculty basement...
They had been working on an experimental device that could copy one persons consciousness and place it into another body. Tests has been going well, until there was a power surge! Causing the machine to go haywire. It exploded. Causing almost everyone on campus to swap bodies!
Chaos ensues. With the swapped students having to quickly acclimatise to vastly different surroundings, and bodies.
The worst part is that it isn't a one to one process. Just because you were put into one body doesn't mean that person got yours. This makes it even harder to determine who is in who's body.
