Day 5 starts and ends at 7:00 a.m. Eighteen months after Day 4, Jack is living under a new alias, as Frank Flynn. He is currently living with Diane and Derek Huxley, a family near the Mojave Desert, California. Meanwhile, an unknown figure orders the assassination of the only four people who know Jack is alive — Tony Almeida, Michelle Dessler, Chloe O’Brian and former President David Palmer — as an attempt to frame him. He returns to L.A. to clear his name, when a hostage situation erupts. It is soon realized that this was only a diversion by a 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 L.A. in retaliation after they discover a U.S. agent has infiltrated their organization. Jack attempts to search for the remaining canisters and expose treachery that goes deep within the White House.
