February 28th. Two fifteen-year-olds in the same class, both with their birthday on the 29th. Manon is a bit of a rebel and comes from a disadvantaged background whereas David is from a “good family”. This is not a leap year though and the next day is the 1st of March. But at 7:41 sharp on March 1st, time stops still. At the same moment a explosion is heard. Manon and David are both terrified. Everybody is frozen and the cars stop all over the city. It’s like a massive living statue contest! Soon a group of people, young and old, take charge of them and explain the situation. They are all Bartholons, born on February 29th and each non-leap-year, people like them enjoy an extra 24h to live while the rest of the world stand still… The two very different teenagers embarc on a fantastic and dangerous adventure in the motionless city. Surviving these 24h is not going to be easy.
