Pierre-Louis Cinq-Mars is a successful stockbroker. Everything in his life is well-ordered -- stock investments, luxury car, the latest computer, stylish and tasteful clothes...well-ordered to the point of being utterly predictable. Jackie Pigeon, the owner of the Camping Pigeon campground, is a go-getter who always gets her way. She conducts her business with a sure hand and everything at the campground runs smoothly. Her life is the complete opposite of Pierre-Louis's -- she's rather messy, of modest means, wears flamboyant and sexy clothes...everything in her life hovers on the edge of bad taste. Two people from completely different worlds whose paths would not normally have been fated to cross.

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.
