Bud Abbott and Lou Costello are a pair of mild-mannered bookworms who pose as big game hunters travelling deep into the African jungle in search of a rare gorilla - but what's really at stake is a secret diamond mine. Along the way they'll tangle with lions, cannibals, criminals, and, of course, wild apes! Their accomplices include the lovely Hillary Brooke (who later appeared on their TV series) and Three Stooges co-horts Shemp Howard and Joe Besser - plus, cameos from real-life lion tamer Clyde Beatty and bug-game tracker Frank Buck.
