At a cancer research lab off the coast of Ireland, a group of scientists dies under mysterious circumstances. Before anyone notices their demise, the human and bovine inhabitants of the island's lone, tiny village begin to turn up dead -- with their bodies the consistency of tapioca pudding. Renowned bone doctors Brian Stanley (Peter Cushing) and David West (Edward Judd) are dispatched from the mainland to solve this medical mystery. West's rich-girl paramour, Toni Merrill (Carole Gray), bribes her way into the expedition by providing air transport. When daddy needs his plane back, the group becomes trapped on the isolated island just as the true extent of the science-run-amok menace becomes apparent. One of three films Hammer horror vet Terence Fisher lensed for small British outfit Planet Studios, Island of Terror was followed by Island of the Burning Doomed. ~ Brian J. Dillard, Rovi
