The movie chronicles the long, futuristic voyage of a team of Québécois space explorers looking for a planet capable of sustaining life, in the year 2034, after the destruction of the ozone layer through excessive human pollution, prompting the need for a new planet to welcome humankind. The seven crew members venture outside their own galaxy to explore other star system in search of a new planet large enough to sustain 6 billion people. The few habitable planets encountered are ultimately abandoned either because they are already occupied (emphasizing the wrongdoing of invading other civilizations and cultures), or because upon closer inspection they are found to have other problems (cow-sized mosquitoes, high radiation levels, dog overpopulation, unsuitable living environment, ...).

Jean-Charles has an unusual relationship with his mother. He can't break free of her influence even when writing his master's thesis, made up of interviews with the several hundred men who have slept with her. Jean-Charles can identify -- he's one of them. But the incestuous bond between mom-and-son is jeopardized when Jean-Charles meets Cassandra, and Mom shifts her attentions to a hot young stud in retaliation.

Brother Marie-Victorin was 46 when he met 23-year-old Marcelle Gauvreau. Both have been close to death and share the same love of God and Nature. He becomes her teacher, later she becomes his assistant. Their friendship evolves. Marie-Victorin offers Marcelle different readings on sexuality that she hastens to comment on from her own intimate experiences. In an epistolary exchange that will last until the death of Marie-Victorin, they explore human desires and "biology without a veil". This great chaste love, the love of Quebec's flora, pushes them to question their own relationship with love and Nature.
