In this thriller, shot on location in Rhodesia, an American insurance investigator looks into the strange death of a diamond broker who drowned while diving for diamonds off the African coast. The broker had been insured for over $1 million. The sleuth's prime suspect is the broker's fiancee. He trails her as she goes on a dangerous safari. He quickly finds out that the broker isn't dead at all. The two had designed the scam to raise money for the dive. The agent and the crook engage in a canoe chase that culminates in the crook's capture. ~ Sandra Brennan, Rovi
