Businessman Frank Deane is found dead with his face and hands burned beyond recognition.

Detective Patrick (Langton) pursues and arrests Deane's girlfriend, nightclub-singer Eden Lane (Payton).

Patrick, who has developed a romantic interest in the woman, believes her; he and Eden jump from the train to search for the man.

The situation has, naturally, put Patrick in legal jeopardy as well and he is eventually tracked down by his friend and superior, Detective Rawley (Shayne).

Eden, in the meantime, convinced that the truth cannot be unveiled, furtively leaves Patrick and turns herself in.
