In June of 2016, a young woman called Mary find herself trapped in a familiar house, with almost all of her memories gone. The windows are unbreakable, and the doors locked. Connected to the internet through a notebook, but without being able to reach out anyone, and armed with a camera, Mary starts registering her new routine as she attempts to make sense of her situation and of a few strange occurrences in the house. During the day, nothing happens. But at night, things are very different. Based off the hiimmarymary series.
