A film-opera divided into nine segments, Au pays de Zom tells a day in the life of Mister Zom, a capitalist infatuated with his own person, whose conformism is only matched by his artistic velleity. A thematic sequel to his movie filmed with Mexican peasants, here Groulx asks, by making a business man sing, a second question on happiness: this time about the ones for whom happiness is linked with the possession of overabundance.
