Locked in a cement grave for decades, under the bowels of the lake, an abandoned government fallout shelter is crawling with genetic hybrids, and toxic mutants.
This maze is set in the 1950's during the Cuban Missile crisis and President Kennedy has ordered to have all the large fallout shelters to be closed. Everyone is packed in and this particular Shelter gets a communications error, the fallout shelter is sealed and never reopened again. The head Doctor in charge goes crazy and doesn't let anyone out and starts to experiment on all the people inside and cause all kinds of mutations.
