Shades of On the Waterfront or a fistful of other boxing dramas where the fix is in.
Vincent Gardenia plays Bull. A mobster that controls the local boxing. His goons make sure that Bull has a stake in any up and coming contender.
Lenny Capper is one such promising contender. Bull hospitalises his trainer Hecky a few hours before the next fight that Lenny loses.
Casey Jones catches Bull intimidating Lenny's girl. Casey wants to know more about Bull. The police have not been able to make anything against him stick in the past.
This is a well trodden path. You would think an experienced trainer like Hecky would have a handle on how to treat people like Bull or atleast watch their back after rebuffing their advances.
As for Lenny, the future's bright, the future's orange.
