Football player Bob Miller (played by football player Bob Waterfield) gets lost in the jungle and is searched for by a female reporter who teams up with Jungle Jim. She wants to make a mint by taking photographs of him - Jim reminds her of the dangers of doing things for money.
They subsequently stumble upon a crazed doctor who has been kidnapping villagers to work in a radioactive mine, where he has discovered a way of making diamonds out of mineral rocks.
Starts out in its usual manner, full of peril with skeletal men and it's appears that it'll be a routine, yet watchable adventure, then in the last thirty minutes or so the throttle increases and it's just one cliffhanger to another with Jungle Jim taking on a Bond-like villain named Dr Heller, who likes to tell his prisoners ( Jim, Miller and the sexy Shiela Ryan) his plans. Just like a Bond villain. There's an octopus' fights, dynamite being stuck in a shark, cave holding diamonds getting flooded - they are mainly stock footages but it's done expertly. The plot is much stronger than usual with limited lengthy animal interludes, and the idea of a football player leading an inhabitants and helping them is a wild idea . It's a fun piece of hokum, not to be taken seriously, but enjoyed for its outlandish approach.
