The Man from B.U.N.G.L.E. receives a tip-off that his arch-enemy, Dr. Doom, has flown to South America in the hope of making-off with a vast horde of gold recently discovered deep in the jungle. So, having hired a horse from a solitary outpost, he is soon in hot pursuit. However, the wily doctor is waiting in ambush. Larry comes round to find himself roped to a pole on the edge of a rising river, infested by man-eating fish.
