Katorga 12 is a research facility manned by the Soviets in the 1950s

Katorga 12 is a research facility manned by the Soviets in the 1950s. As events transpired, a fatal accident resulted in the island's closure, but the base remains in a derelict state. In the present day, an American satellite becomes victim of an electromagnetic shock that seems to come from this island. As Cpt Renko is drafted into the island, his plane crashes because of an EMP. Deciding to explore the island, he uncovers evidence that the Soviets were experimenting with a substance known as \when time reverts itself. As mutants scurry around the island looking for their next meal, the two Americans are captured by an apparently Soviet based army. While his partner is executed by the man he once saved, Renko is saved by an operative from a secret organisation who explains the consequences of his paradox. Somehow he must find a way to return history to the timeframe he knows; otherwise Dr Demichev will still remain president of the world.
