When a woman is killed at a swinger party, her father seeks revenge. A young woman finds out her sister had died in the home of two brothers who run a cosmetics company; she comes to Frank Cannon to investigate the circumstances of her death, and who may have killed her during a swinging affair.

A couple hire Cannon to get their son out of a Turkish prison. A young man is persuaded to extort his own father for $50,000 but his father is found to be bankrupt; Frank Cannon is called upon to investigate the disappearance of the money, which may or may not be connected to drugs.
