The complete fifth season of the real-time drama series. 18 months after Day 4, Jack is living under a new alias, as Frank Flynn, and working on various oilrigs and refineries throughout America. He is currently living with Diane and Derek Huxley, a family near the Mojave Desert, South Eastern California. Meanwhile, an unknown figure orders the assassination of the four people who know Jack is alive–Tony Almeida, Michelle Dessler, Chloe O’Brian and Former President David Palmer–to frame him. He returns to LA to clear his name when a hostage situation erupts. But it is only a diversion by collaboration of conspirators and Russian separatists to obtain 20 canisters of Sentox VX nerve gas. The gas was originally to be used to attack Moscow, but the separatists begin to release it in LA in retaliation after they discover that a US agent has infiltrated their organization. Jack attempts to search for the remaining canisters and expose treachery deep within the White House.
