Watch La venus maldita

In a small fishing village, the residents of the town have discovered something mysterious under the waters of their large lake. Joe, the leader of the town's union of fishermen, has heard reports from some of the other fishermen of seeing beasts in the shape of men swimming below the waters. They let off an unearthly glow and sing a terrible song which has driven some of the fishermen mad. Joe finds an antique diving suit and makes his way to the bottom of the waters. What Joe finds there not only shocks him, but can change science underwater forever.
