Sam wakes up and can't remember anything. Has she been in an accident-a car crash, perhaps? She's also in an unfamiliar place. She could be in a hospital. In the darkness, she concludes it must be a hospital. Surely a nurse will come check on her any moment, right? No, something was definitely wrong with this place.
With no memory of how she got there, Sam slowly begins to panic as she realizes she is trapped in a strange facility with no escape. To make matters much, much worse, a murder has taken place.
There is no one to trust and danger around every corner. If Sam isn't careful, she'll end up the next victim. She must find a way to survive, but the only way to do that is to regain her memories. Sam has to uncover what's really happening in the facility and how she got there in the first place. It's her only chance to find freedom and live.
