The first season of Severance on Apple TV+ follows the employees of Lumon Industries who have undergone a procedure to separate their work and personal lives. This procedure creates two distinct personas: the “innie,” who only exists at work, and the “outie,” who only exists outside of work. The story centers on Mark Scout, who leads a team of severed employees, including Helly, Irving, and Dylan. As they begin to uncover the dark secrets of Lumon Industries and the true nature of their work, they face moral dilemmas and personal conflicts that challenge their understanding of identity and freedom.
