June 1999. It's the high school prom for the gang. Its members have set up the 2000 project: videos where each and everyone presents their life goals for the next 10 years. But an incident that occurs after the ball has the effect of a bomb for Vincent, his half-sister Catherine, his girlfriend Stéphanie and his best friend Youssef. These young people will not wait 10 years to succeed in their 2000 project! All their experiments must be done, and faster than expected.
