A strange radioactive glow in the water is followed by an attack by a bizarre looking creature. Dr Stevens (Kent Taylor) arrives to investigate and finds that local scientist Professor King (Michael Whalen) is acting suspicious. Stevens also romances the Professor's daughter Lois (Cathy Downs) of course!
So, this is pretty much all you expect from the genre. The monster doesn't look too bad and isn't over shown but the rubber suit was obviously a bit clumsy for the actor wearing it. In one scene where it attacks a diver the monster looks more like a nervous teenager doing some awkward fumbling than a mutant killer beast! The story is a bit slow but ticks all the usual genre boxes.
Perfectly acceptable time waster.
