Weasels Rip My Flesh

Returning from the planet Venus, a misdirected NASA spacecraft crashes into the ocean, spilling its radioactive cargo. Enveloped by a radioactive mist, a rabid weasel mutates into a colossal killer. Roaming the countryside, the enormous weasel stalks and devours its victims. The creature is captured by a troubled scientist who intends to harness its regenerative blood to forge an army of similar monsters, enabling him to conquer the Earth.
