Jack is back!
In the two-hour premiere, Jack is in London to attempt to thwart an assassination attempt on President Heller (William Devane). But that's not his only problem. CIA Agent Kate Morgan (Chuck alum Yvonne Strahovski) is hot on his trail and his old sidekick Chloe (Mary Lynn Rajskub) has had one hell of a scary makeover.
