Severance

The premise is almost purely formal: a surgical procedure splits a worker's memory clean in two, so that the person who clocks in has no knowledge of the person who clocks out, and vice versa. Dan Erickson builds Severance around that division as both a workplace thriller and an identity puzzle, letting the office floor operate as a hermetically sealed world that gradually reveals its own strangeness from the inside. Adam Scott anchors it — his severed self navigating corridors and quarterly reports with no horizon beyond them. The show's method is slow accumulation: each episode tightens what the characters can know, and the audience's advantage over them remains narrower than expected.
