Against The Ropes (2004)

At a young age, Jackie Kallen learns about boxing with her father and uncle in a small gym. Later, she becomes the assistant to a Cleveland boxing promoter. Her boss then begins doing business with Sam LaRocca, a sports manager, during a middleweight championship fight. LaRocca asks afterward what she thought of the fight. Obviously unimpressed with Jackie's knowledge of boxing, LaRocca offers her the loser's contract for a dollar. She goes to visit the fighter at home, only to find him addicted to drugs. Enter Luther Shaw, a small-time hood. Kallen watches in horror and fascination as Shaw pummels the former middleweight champ. She offers to manage him professionally. Shaw is at first hesitant, but he eventually signs on with her.
