Marty discovers a hidden map-like clue and learns about maintenance routes that don't appear on any official layout. Carter makes it clear: Marty isn't being asked to help-he's being drafted.
Marty is framed with contraband and dragged into a disciplinary “trial.” Halden and Briggs tighten the pressure, forcing Marty into a dangerous choice: tell the truth and die, or stay silent and be owned.

Carter reveals his true nature and shows Marty the maintenance pathways that don’t exist on paper. A risky test run proves the escape route is real—but it will require a major distraction to work.

A lockdown seals the prison and becomes the cover for Carter’s next move. Marty is pushed through a critical hatch into the laundry/service side—only to be trapped when Briggs closes in.

The distraction erupts into a full riot, and Carter uses the chaos to force a path forward through restricted corridors. Halden responds with full containment, turning the prison into a tightening net as the escape window shrinks.

Marty survives the immediate fallout, but the final moment changes everything — the island isn’t finished with him. In this gripping Season 1 Finale, the fate of escape, loyalty, and survival collide, setting the stage for what comes next.
