Andre has died under mysterious circumstances leaving behind his wife and two daughters. The youngest daughter desperately tries to fit in with the other adolescent girls in her new school while her older sister finds a lover for the first time : a man much too old for her. Meanwhile, their mother is preoccupied with paying their bills. She does not see that her family is in danger of drifting so far apart that they may never find each other again. Dérive is a deeply empathetic portrait of these women's odyssey from frailty to resilience.
