At the mysterious Lumon Industries, employees can undergo "severance," a surgical procedure that splits their consciousness so their office selves retain no memory of their outside lives, and vice versa. Mark leads a small department of these divided workers who toil at cryptic tasks, knowing nothing of who they are beyond the sterile corridors of the severed floor. When a colleague resurfaces on the outside and cracks begin to show, the team starts unraveling the sinister purpose behind their own compartmentalized minds. Coldly stylish, unnerving, and darkly funny, it's a cerebral corporate thriller about identity, control, and what it means to be free when half of you is imprisoned.
