Bog

In this 1979 American independent horror film, a rural swamp serves as the unwitting incubator for an ancient gill monster, awakened by dynamite fishing. The creature's grotesque visage and malevolent appetite for human female blood lead to a series of gruesome killings, prompting a local sheriff to take matters into his own hands. As biologist Ginny Glenn discovers the creature's evolutionary nature, the body count rises, culminating in a violent showdown that leaves the beast defeated but its eggs lingering ominously.
