This is the film’s tagline:
A Penetrating Look Into the Sordid World of Bruises and Broads
It’s a Harry Novak production so do not expect a great history, but here it goes: a boxer’s manager pays a prostitute to make his boxer’s nights hot, and endless. Not so strange, considering all the dirty deals the manager has with the local mafia. The strong champion has to contend with the sexy girl, before he gets to the ring with the title contender. But there are other interests at play, and more girls to play.
