Lost in the African jungles for over a year, Dr. Charles Decker (Michael Gough, The Crimson Cult) has returned to England with Konga, a baby chimpanzee. Disappearing into his lab, the mad botanist begins work on what he believes will be his greatest achievement. Having witnessed a Baganda witchdoctor’s use of a rare carnivorous plant to produce accelerated animal growth, Decker injects Konga with the same serum—then hypnotizes the gorilla-sized chimp into brutally murdering his enemies! But when the berserk ape overdoses on the serum and grows to gargantuan size, suddenly the city of London comes under attack—and only the British army can reckon with Konga’s uncontrollable rage. John Lemont (The Frightened City) directed this monstrously enjoyable cult classic.
