Contact has been lost with a top-secret research lab, and Agent 'X' is sent to find out why. When he arrives at the island where the laboratory is located, he discovers all the staff dead, their bodies mutilated by horrendous radiation burns. However, the silent dead are not the only witnesses to his investigation, and another is watching his every move. Too late, Agent X realises that a death similar to that inflicted on the staff - by a hand that is not human - will be meted out to him. His options are limited - escape or die!
