Season 8 is a barn burner. Middle Eastern terrorist on American soil, Russian ex-military mafia, lose nuclear materials, CTU in NYC, a female US president, a familial traitor, an EMF detonation, and a deadline to finalize a peace treaty before a dirty bomb gets deployed in Manhattan drags a retired Jack Bauer back into a devastating whirlwind that almost destroys him. Chloe returns as a underdog CTU analyst who has to fight the new administration to keep everything in the air while Jack deals while reuniting with Renee Walker and her renegade approach to intelligence gathering. Excitement, violence, revenge, and chaos ensue. Good vicarious adrenaline fun.
