They say that New York is the city that never sleeps.

Well, we're anxious to see what happens when the Big Apple meets the CTU agent that never sleeps!

Indeed, the scene shifts from Los Angeles to NYC on season eight of 24, as residents of the latter city should prepare to get Jack'd. That's what the new Fox teaser poster warns, at least...

Other changes to 24 include a dynmate set of recurring guest stars. They'll be led by Katee Sackhoff in the role of Chloe's CTU boss, Dana Walsh.

The action kicks off on Sunday night, January 17.
