Back in Montréal after spending five years in Guatemala, Julie moves in with her elder sister, Jeanne, a chronic liar and woman of rather loose sexual morals... Disillusioned with love, Jeanne is nevertheless engaged to Noël. However, Jeanne and Noël lead separate lives, and only communicate by leaving each other messages on the fridge.Everything suddenly becomes very complicated. Jeanne compels Julie to take up with Noël so she can have a fling with a passionate musician. Noël, meanwhile, sets Julie up with Michel -- without Jeanne's knowledge. Julie mixes things up even further. Egged on by her friend Marie-Ève, she alters the contents of the messages on the fridge in an attempt to breathe new life into Jeanne and Noël's relationship. Along the way, she also begins to fall for the seductive Michel. The tables are turned on everyone... In the game of love and truth, illusion leads to betrayal, but love conquers all.
