The city of San Siroco is in a state of decline, with the basement of Dr. Tamsin Rivers, the arrogant and selfish head of the research team assigned to find the source of the subsidence, experiencing a rapid descent. Tamsin's obsession with the distorting dimensions of the room at the bottom of the stairs leads her to discover a door that wasn't there before. One night, as she approaches the door, it mysteriously opens, revealing an exact physical copy of herself. This doppelgänger, unlike Tamsin, is sweet, biddable, and seemingly fully human, passing every test Tamsin can devise. However, as time passes, Tamsin begins to forget pieces of her life, lose track of time, and become terrified of the outside world.

Her employer grows increasingly suspicious of her behavior, and Tamsin must struggle to maintain her sanity long enough to figure out what her double wants from her and where the mysterious door leads. As she delves deeper into the mystery, Tamsin discovers that her double has a dark secret, and she is forced to confront the truth about herself and the city's impending doom.

In the end, Tamsin must make a difficult decision that could save the city or lead to its destruction. She must confront her double and face the consequences of her actions, knowing that the fate of San Siroco rests on her shoulders.
