Obese general store owner Bruno Ve Sota is married to sluttish teenager Yvette Vickers, who is cheating on him with his best friend, Michael Emmet. The trio ends up in the swamp, Ve Sota literally hunting down the adulterers with a shotgun. That situation alone should have made for an interesting tale, a sort of humid James M. Cain for the beat generation. But this is a Roger Corman production and into the mix are thrown a couple of stunt divers wearing what appears to be small ponchos with tentacles, the leeches of the title, and a hunky game warden (Ken Clark), who displays a disconcerting ignorance of alligators, the game he is hired to protect. The results are uneven at best but the swamp locations, filmed at Pasadena's Arboretum of Tarzan fame, are certainly picturesque and the cave sequence, photographed, according to co-star Yvette Vickers, at the old Charlie Chaplin Studios, at least somewhat creepy.
