Montreal 1944, where Prohibition is non-existent, shines with all its vices: gambling, women and alcohol. Lili St-Cyr, the fascinating and bewitching stripper, makes a remarkable entry onto the cabaret scene, turning the lives of the characters gravitating around Théâtre Gayety upside down. Through her freedom to choose her professional life, Lili inspires women to question their destiny and take control of their lives.
