It's summertime, and the kids are heading to the beach for the French version of spring break. Brother and sister Matthieu and Léa have hitched a ride with Sam -- an older, brooding Heathcliffe type with a gun in a plastic bag and a troubled past.

Now it's Matthieu's turn to move in on strong and silent Sam.
