The Beast of Borneo

A noted big game hunter, Bob Ward (John Preston), is visited in the jungles of Borneo by Russian scientist Boris Borodoff (Eugene Sigaloff) and his lovely assistant Alma Thorne (Mae Stuart), who want to prove the evolutionary link between man and beast. Ward at first declines to lead the scientists to a tribe of orangutans, but Alma's charms finally convince him. Along with Ward's pet orangutan, Borneo Joe, they track the apes and actually manage to capture a male orangutan, whom Dr. Borodoff anaesthetizes with a shot of whiskey. Borodoff, it soon appears, is quite insane -- and Bob, in an effort to calm him down, is knocked unconscious and dragged into the jungle by the tormented orangutan. He is rescued by Alma and Borneo Joe, but the trio can only watch as the enraged simian kills the evil Dr. Borodoff.
