Emma has an unremarkable life: a mundane job, very little contact with her family, and no significant relationships. Night after night she drinks tequila to forget until one evening she is jolted out of her routine. She’s kidnapped by two masked men and wakes up in a concrete room furnished with only a mattress on the floor and a ceiling lamp. Suffering extreme thirst and alcohol withdrawal, Emma is seized by real emotion for the first time in a long time. At first, she tries to make sense of what is happening to her, where she is, and who kidnapped her, but as the days, weeks, and possibly months stretch on, she develops a new routine that involves stretching, drawing on the walls, running in circles, and drinking the strange solution that is provided to her by some unseen person. It occurs to her that life in the room is much like the life she had while she was free. Just as Emma begins to find comfort in her routine, she wakes to find a man in the room with her. Though she is initially disturbed and frightened by his presence, a connection slowly develops between the two. Emma comes to rely on the man as the two are subjected to various tests, including sensory deprivation, and they come up with a daring plan to escape.
