Gino Felino is an NYPD detective from Brooklyn who knows everyone and everything in his neighborhood. Killing his partner was someone's big mistake... because he's now out for justice.

John Arnold DeMarco is a man who believes he is Don Juan, the greatest lover in the world. Clad in a cape and mask, DeMarco undergoes psychiatric treatment with Dr. Jack Mickler to cure him of his apparent delusion. But the psychiatric sessions have an unexpected effect on the psychiatric staff and, most profoundly, Dr Mickler, who rekindles the romance in his complacent marriage.
