Province of Quebec, Canada, the Maple Spring, 2012. Driven by frustration and the desire to find a new life, Klas Batalo, Ordine Nuovo, Tumulto and Giutizia form a counter-cultural group, a radical cell guided by a deep hostility to the established order that they manifest through terribly ambiguous political expressions, Molotov cocktails and guerrilla tactics, seeking to sow mayhem in Montreal as a prelude to the overthrow of the government.

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, ...).

In the middle of the night, in the Québec countryside, all hell breaks loose as a black teenager is caught smashing a racially denigrating lawn ornament. Together the neighbours attend to justice against the vandal. Thorough the night there is mounting racism, fueled by alcohol, and violence. Le Nèg' opens the morning after when the police investigators arrive at the scene to take depositions.

On the eve of her final moments, a woman recalls her alcoholic past. She revisits her entire youth, including a binge that, at 46, cost her everything she had: "Loneliness and aging are themes that impose themselves on me, in one form or another. As for alcoholism, it fascinates me because of the revolt it underpins, and revolts me because of the unhappiness it creates around itself.
