Adelaide Carmichael knows that she's lost her mind.

She's aware that she's being sent to The Oakhill Institution, but she's been told that she's being sent there to get better. She's been told that the staff is there to help.

And it doesn't take Adelaide long to discover that she was very, very wrong about The Oakhill Institution. Patients roam the halls like zombies. Electric currents vibrate through the plaster walls. Patients are fed sedatives like mashed potatoes and now Adelaide knows one thing for sure, she wants out.

And she'll do whatever she can to escape.
