Operation Wedded Bliss: will Chuck and Sarah finally become Mr. and Mrs. Superspy? Season Four's 24 laugh- and action-filled episodes include the duo's romance from proposal to planning to the big day. Yes, Chuck's in love, but he has more than romance (and the Intersect) on his mind. His mom comes in from the cold, escaping the evil control of an international arms dealer to become part of the Nerd Herder-turned-spy's life - and making it even tougher for Chuck to keep his professional and personal worlds separate. On some days, Chuck outwits assassins and out-martial-arts hordes of black-clad bad guys. On others, he pursues Sarah and prepares to become a doting uncle. On most days, he does it all!

Now that those closest to Chuck know his secret, he must try harder than ever to keep his spy life from interfering with his personal life. But this has never been more difficult - his relationship with superspy Sarah Walker is getting serious, and he's about to take on his most personal mission yet: finding his mother.
This season, Chuck's assignments take him far from Burbank, with each mission bringing him closer to uncovering what happened to his mom, Mary Elizabeth Bartowski (guest star Linda Hamilton, "The Terminator," "Terminator 2: Judgment Day").
The ever stoic Colonel John Casey (Adam Baldwin, "My Bodyguard," "Serenity") returns with partner Sarah Walker (Yvonne Strahovski, the upcoming "The Killer Elite"), one of the CIA's top agents and Chuck's new girlfriend.
