A regular 26-year-old everyman has his life thrown into disarray after his friend, a CIA agent, sends him an e-mail that results in the world's secrets becoming embedded in his mind.
In season three, Chuck finally has the potential to become a real agent. There's just one problem — his emotions. Can Chuck keep them in check as he assumes his new role as the Intersect 2.0? His handlers, Sarah Walker and John Casey, will still be there to protect him, but they also must help him become the agent he is destined to be.
With Chuck's new Intersect abilities — resulting from a data upgrade and some actual spy training — he is now fully equipped with deadly fighting skills and ready to face the Ring. Can Chuck truly become the spy he longs to be, or will his emotions continue to get in the way?
The fifth and final season continues from the cliffhanger ending of the fourth season finale. With the help of his unlikely team and unorthodox techniques, Chuck is ready to take Operation Bartowski freelance. Chuck’s spy abilities will be put to a new test when he and his team must save mankind without the help of the CIA. Instead, they'll use the cover of the Buy More electronics store to fund their own operations, leading to new missions, new stakes and new obstacles.
