In a small town in Quebec, the tide suddenly stops. It is her birthplace, so seismologist Alice (Pascale Bussières, La Repetition, Girls Can't Swim, Emporte-moi, When Night Is Falling) is sent to investigate. There she gets involved in a local story about a woman who died in the bay, and she becomes attracted to Marc (Jean-Nicolas Verreault), the man who lost his wife. At the same time, Catherine (Julie Gayet) arrives to cover the story for a magazine, knowing that Alice may be there. They're old friends from college, and Catherine is in love with her.

It's an odd story about longing and sensitivity, with beautiful and stunning photography. Alice and Catherine are both sexy and sensual, as part of the mood of the film, although they do not end up with one another. It seems part of the natural rhythm that Alice connects with Marc, and Catherine hooks up with a local female cop ... and the tide comes in again.
