(CBR) After four years off the grid, both Jack Bauer and "24" are making a comeback.

The new trailer for "24: Live Another Day", Fox’s resurrected real-time thriller, puts Bauer back in the spotlight. Four years after he fled the United States as a fugitive from justice, Bauer has reemerged in London, ending an extended period of radio silence for reasons the authorities can’t quite explain.

Is it a coincidence that Bauer is in London at the same time as President James Heller, the man who, as Secretary of Defense, employed the counter-terrorism agent? The same man who all those years ago warned Bauer to stay away from his daughter, Jack’s former flame Audrey Raines? It’s not a chance the CIA is willing to take. But smart money says that if there’s an assassination attempt on Heller’s life, it won’t be Bauer behind the bullet — it’ll be Bauer on the assassin’s tail.

Starring Kiefer Sutherland as Jack, Mary Lynn Rajskub as hacker Chloe O’Brian, William Devane as James Heller and Kim Raver as Audrey Raines, "24: Live Another Day" premieres May 5.
