This season, Chuck is in luck. Intersect II is ready for espionage service. And that means the old Intersect (Chuck) can go back to his old life. But if Chuck goes, he's gone: Casey has orders to off him. Chuck survives to unravel mysteries of the past, become a hero in the present, and - in a stunner of a season finale - chop-and-drop himself into an even more perilous future!
