A surgeon saves an notorious mobster's life. This could be the answer to the doctor's problems, as he is engaged to an unbearable, hysterical woman. The mobster agrees to assassinate her. Except for one thing. The mobster has the wrong target, a young, innocent journalist who resembles his fiancee.
