The Mod Squad sets to work busting an extortion racket run by a self-styled healer responsible for the death of Linc's friend. Julie befriends a wheelchair-bound man paying large sums for empty promises that his paralysis will be cured.

When his motorcycle breaks down on a trip, Linc stops in an abandoned town, only to discover that a kidnapped boy is being held there for ransom. The kidnappers decide to hold Linc as well until they get the money.

A fur coat is the only lead the trio has in a case involving kidnapping and murder that has them baffled.
