At Bletchley Park, Alan Turing must persuade a skeptical team to build a machine that can break Enigma before the war is lost, while concealing the self the law condemns.
- Scenes 1–12
Turing is investigated as a guarded outsider in 1951, then enters Bletchley in 1939 looking for the puzzle he can solve.
- Scenes 13–30
He sees the scale of Enigma, believes a machine can solve it, and grows isolated from colleagues who make little progress.
- Scenes 31–50
Churchill’s order gives Turing authority and his half-built machine advances toward sustained work.
- Scenes 51–88
Joan joins the project; the team builds and tests the machine while Turing learns to rely on collaborators.
- Scenes 89–91
A first decrypt proves the machine works, and the team immediately faces the choice to let the Carlisle convoy be attacked.
- Scenes 92–120
The team applies Ultra selectively, accepts wartime losses, and carries the burdens of secrecy through the end of the war.
- Scenes 121–123
At Bletchley’s closing wartime order, the story returns to the 1951 interview where Turing asks Nock to judge him and then shows the conviction Nock failed to prevent.

- Scene 124
Turing, visibly weakened and limping, struggles over his newer machine until Joan arrives after learning of his conviction from the newspaper.
- Scene 125

Young Alan sits beneath Christopher’s tree with the book Christopher gave him and cries alone.
