Severance is a psychological thriller series created by Dan Erickson and directed primarily by Ben Stiller, streaming exclusively on Apple TV+. The series is set at Lumon Industries, a mysterious corporation where employees have undergone a surgical procedure called severance — a process that creates a complete separation between their work memories and their outside lives, producing two distinct versions of each person who share a body but experience entirely separate existences.

The series stars Adam Scott as Mark Scout, a severed Lumon employee whose work self begins to question the reality of his world when a new colleague named Helly (Britt Lower) arrives and refuses to accept her situation. The ensemble includes Zach Cherry, Tramell Tillman, Jen Tullock, Dichen Lachman, and John Turturro, with Patricia Arquette and Christopher Walken in pivotal supporting roles. Ben Stiller's direction transforms Lumon's brutalist, fluorescent-lit office into one of television's most unsettling environments — a place that is mundane and horrifying in equal measure.

Severance premiered on Apple TV+ in February 2022 and returned for a long-anticipated second season in January 2025, both of which were met with widespread critical acclaim and a devoted audience. The show has been celebrated as one of the defining works of prestige television in the 2020s — a slow-burn corporate horror story with profound things to say about identity, autonomy, and the fracture between who we are at work and who we are when we go home.
