"Hit Big" revolves around Marjaleena, a 60-year-old, boozed-up former beauty pageant star who left Finland for Spain's Costa del Sol where she runs Bar Belle, once a popular spot for Finnish tourists, with her handyman Mikko. One day, they hear that Marjaleena's husband, Worm, will be released after 20 years in prison and is planning a dream life with his cell-mate lover thanks to the stashed proceeds of a major heist. Feeling betrayed, Marjaleena sets off to get her share of the millions.
