A couple (Rosemary Forsyth, Guy Stockwell) being blackmailed hires Mannix when it appears the wife, not the extortionist, may go to jail.

Mannix investigates the death of a woman on a ski slope and finds she was murdered because she was the wrong target of a kidnapping attempt.

Mannix can't find the lady who he saw being attacked in her yard by 2 men, but he does find out that a woman was murdered there under the same scenario a year before.

Joe Mannix once again returns to his hometown in California's Central Valley, this time to assist Armenian attorney Leo Kolligan in defending Juan Esparza, a farmworker accused of murder.

Joe Mannix is approached one evening by a woman named Lisa Ralph, who says that she believes someone may be trying to kill her, possibly because she has a valuable manuscript that she inherited from her late father.

Mannix uncovers a hidden identity when a woman hires him to rescue her alcoholic brother (Vic Morrow) from skid row.
