Mark Scout is a grieving widower who voluntarily undergoes the severance procedure at Lumon Industries, surgically dividing his consciousness so that his work self ("innie") has no memories of his outside life and vice versa. He takes the procedure as a way to escape the pain of losing his wife Gemma, effectively numbing himself for eight hours a day. As the head of the Macrodata Refinement department, Mark's innie leads a small team performing cryptic data sorting tasks whose purpose none of them understand.
When his new colleague Helly arrives and desperately tries to escape, Mark begins to question the nature of the severance procedure and the ethics of Lumon Industries. Guided by clues from a former colleague and the mysterious "revolving" phenomenon, Mark's innie becomes increasingly rebellious, forming alliances with Irving and Dylan to uncover what Lumon is truly doing on the severed floor.
The collision of Mark's two lives reaches a shattering climax in the Overtime Contingency, when his innie temporarily gains access to the outside world and discovers that his supposedly dead wife Gemma is alive — working as Ms. Casey, the wellness counselor on the severed floor. This revelation reframes everything Mark believed about his grief, his employer, and the true cost of severance.
