A man recovering from a car accident in a hospital discovers that perhaps he is infected with HIV virus and decides to kill the people he assumed to be responsible. Richard and Rex have to stop a person who has nothing to lose.

A bomb explodes in a toy store window, the third in a string of Gurmann teddy bear bombings. With Rex taking care of a bedridden Richard, Stocki investigates a long list of disgruntled employees. The investigation takes a turn when Richard is visited by the heiress of the Gurmann toy company.
