A revisiting, some 15 years later, of the principal characters of Denys Arcand's 1986 comedy drama film, 'The Decline of the American Empire.' Remy, now divorced and in his early fifties, is hospitalized. His ex-wife, Louise, asks their son Sebastien to come home from London where he now lives. Sebastien hesitates; he and his father haven't had much to say to one another for years now. He relents, however, and flies to Montreal to help his mother and support his father. As soon as he arrives, Sebastien moves heaven and earth, brings his contacts into play and disrupts the system in every way possible to ease the ordeal that awaits Remy. Around his father's bedside, Sebastien also reunites the merry band of folk who were all players in Remy's complicated past: relatives, friends and former mistresses.
