A biopic inspired by true events in the life of renowned boxing manager Jackie Kallen, a middle-aged Jewish mother from Michigan, who guided the careers of several, hi-profile, professional boxers, including four world champions such as: middleweight champ James "Lights Out" Toney, as well as Bronco McKart, and Thomas Hearns. The drama focuses on her relationship with one boxer, in particular, Luther Shaw, a light-heavyweight contender from the inner-city, whose life and career Kallen helped to turn around; and likewise, Kallen's life and career came into focus due to Shaw and his influence on her growth. In real life, Kallen eventually left her husband of 30 years, and moved to Los Angeles, becoming the commissioner of the International Female Boxers Association.
