 In Paris in the near future. Aging thieves Marc and Hans owe money to a tough American woman who gives them two weeks to pay. They scheme to steal and sell a new serum for a disease that s killing lovers, but they need someone with quick steady hands. They recruit Alex, a disaffected youth who s breaking up with Lise, his 16-year-old girlfriend. In the few days before the theft, Alex becomes enchanted with Anna, Marc s young mistress. They talk, they play, they sing, but she s in love with Marc. Lise hasn t given up on Alex either, and she comes to Paris on the day of the theft. There are double crosses, a daring rescue, and, for Alex, a waiting plane. Will he make it?
