The Flanagan Boy (1953)

Johnny Flanagan did not have the privileges of a good education or wealthy background but the streets developed his natural talent to be a great fighter His enormous potential to reach the top is born out of a string of spectacular successes All of which is brought to a halt when he develops a physical relationship with his managers wife the beautiful but manipulative Lorna His naive temperament is no match for her callous dispassionate scheming and he unwittingly becomes a pawn in Lornas ultimate plan to murder her husband
