From info i found about the movie:
"Pictures and clips from Love me if you dare, french smash hit jeux d'enfants. The film is a must see. Overview: Julien meets Sophie at the bus stop and gives her his special carousel tin which his mother gave him. Sophie starts the game of 'dares' saying to Julien 'if you want it, you'll have to prove you do' so then they start daring each other to get the tin back. Whoever has the tin can dare. (something like that) as they grow older is starts getting more tricky, it affects them more and in the end they end the game in a happy/sad romantic way."
