Chuck is back with new missions, a new business -- and no Intersect. The stakes are high as Chuck sets out to become a full-fledged spy. But without the CIA as backup, Chuck will have to rely now more than ever on John Casey, Sarah Walker, and a new Intersect -- Morgan Guillermo Grimes. Across all 13 episodes of this thrilling final season, Chuck will find that his wits, his friends, and his family are the only backup he needs.
