Ray Ferrier is a divorced dockworker and less-than-perfect father. Soon after his ex-wife and her new husband drop off his teenage son and young daughter for a rare weekend visit, a strange and powerful lightning storm touches down.

Set in Montreal during the disco phenomenon some 35 years ago, Funkytown follows the life of a group of colorful characters. We follow their lives and tribulations as everyone converges on a regular basis at Montreal's hot disco spot: Starlight. Along the way, several events take place that change these characters' lives. As these characters' lives unfold, the Parti Québécois takes power changing the cultural landscape in Quebec while the disco craze slowly fades. While we keep up with these various characters - it is Bastien who is a central part of this story. His drug addiction, dreams to become an actor and womanizing - make him the "bigger than life" typical 70s character around which the whole story revolves.
