Dana Andrews stars in this B-grade jungle adventure as an insurance investigator who teams up with the widow (Crain) of a diamond merchant (Farrar) who has apparently drowned after falling from a boat. Cautioned by native guide Vincent (Mataka) that his presence won't be welcome when they reach the village, Andrews persists in his doggedness to uncover the truth about Farrar's disappearance, and in his attempts to seduce the now nubile widow.
Assistant director Tony Kelly died making this picture, so it's of some comfort to know that it isn't a bad little pot-boiler, building some reasonable tension and punctuated with occasional light humour (the scene in which the chimp empties their luggage from the jeep is worth a chuckle). George Montgomery's look-a-like brother Dana Andrews is sturdy without being marvellous, and Farrar plays the obnoxious British git with aplomb.
Superimposing the actors over the white-water rapids backdrop, or in a confrontation with a menacing lion often looks clumsy, but this B-picture isn't staking any grand claims, just mild entertainment for afternoon channel-surfing.
