On a remote island off the coast of Ireland a farmer goes missing and his wife contacts the local authorities. The constable finds the farmer dead in a cave without a single bone in his body and contacts the local physician, who is unable to determine what happened. When a group of scientists are brought in from the mainland it becomes clear that 'test animals' are killing their victims by injecting a bone-dissolving enzyme into their bodies. The creatures prove incredibly difficult to kill. This fantastic horror classic should be part of everyone's collection! (83 minutes - 1966 - Color - 4:3).
