In the year 2064 the USS Legacy carries the surviving population of humankind as its cargo with the goal of regenerating the radiation poisoned Earth atmosphere. However, the brilliant, but evil, Lt. Col. Trevor Durbin has other plans for the Legacy. In a bloody battle, Durbin and his gang of convicts take control of the ship. He plans to detonate the nuclear core of the station, annhilating all but a handful of the remaining human population, descending to the new Earth as Adam -- the original seed of future generations and ruler of his hand-picked disciples. Durbin's plan is challenged as Amos Tucker and a few loyal crew members piece together their last chance at survival.
