Kent Taylor stars as a government investigator, working undercover. When first we meet him, he says his name is Ted Baxter (no relation to the pompous anchorman). Then, he claims his name is Ted Stevens (no relation to the disgraced Alaska senator). Fortunately, the film ends before he claims his name is Ted Bundy. But on to the plot. Something is killing people in the water. The source of the problem seems to be a radiation beam, created by Dr. King (Michael Whalen). The radiation has also created a creature - a shocking development. King's daughter is played by Cathy Downs, a lovely actress who had a good career start in the 1940s, then fell into crap like this. Ms. Downs is around 31 in this film; unfortunately, she looks at least 40. Philip Pine plays a spy who spends much of the film hiding in the bushes with a speargun. Helene Stanton appears briefly as a blonde in a bathing suit. By this time, you'll be asleep anyway.
