Julie fights in underground bouts until Gina, the twin sister she has not seen in thirty years, finds her. Gina is a wealthy woman facing terminal cancer, trapped in a marriage with a philandering husband and three unruly children. With her dying request ringing in Julie's ears to hold the family together, Julie steps into Gina's life and its luxury. Nobody expects the quiet stand-in to change anything, yet she starts bringing order to the household with her fists and confronting the husband's betrayal head-on.
