Ryan is forced to protect a kingpin's son at a golf tournament, otherwise Malcolm's life is forfeit.
Pete tags along when Mac attends a reunion of his old police buddies, but the event takes a dark turn as someone is killing off the attendees one by one.
Mac reacquaints himself with a number of people he hasn't seen in years after he and Pete reopen the case of a glamorous actress who was murdered 30 years earlier.
Pete becomes a rather overage soccer goalie (Robert Wagner, though he looked younger, was 47 at the time of filming) in order to figure out who killed the team's previous goalie and how (the killer uses a camera with a special attachment which shoots a poisoned dart).
Switch is an American action-adventure, tongue-in-cheek detective series starring Eddie Albert and Robert Wagner, who work as private eyes, for a deceptive sting operation. It was broadcast on the CBS network for three seasons between September 9, 1975 and August 20, 1978, bumping the Hawaii Five-O detective series to Friday nights.
