L'un dans l'autre

Thomas is a student in his early twenties. He learns the art of motion picture and direct his first short film soon. Among his crew, there is Loris, his best friend, and Andrea, the girl of his dreams, who is lusting after him for some time. Thomas' life is about to change dramatically the day when, further to a (lucky) coincidence, he swaps his body with an other Thomas, who he absolutely does not know. What can you do when you take full control of a stranger's life ?
