The film follows the story of three girls in contemporary Paris. One searches for her lost mother since she knows she's adopted. The other has come out of a coma and needs to have a love relationship aside from his mysterious father. The third one is a crook who redeems herself through love. The action is commented by songs and dance routines.
The story is said to follow a pair of loner college undergrads, Jack and Montgomery, who order a take-out pie, but accidentally take a homemade drug that turns a two-floor journey downstairs into a “mind-bendingly transformative quest.”
