Marked for slaughter.

Lady visits worlds largest insane asylum. She meets a manic woman who says a friend knows her name. She entertains the conversation and ends up meeting the friend.

The building goes on lockdown.

The manic woman tells her to put on a jumpsuit to blend end- people are being murdered left and right for their clothes. She is given a box and told to keep it safe as the manic woman is killed in front of her. The male friend protects her and keeps her safe. Hurting others in the process.

After the asylum is taken back by police she is stuck in the asylum as a patient. No one believes she is a visitor for a few reasons: the paperwork was burned (visitor log, entry paperwork, patient paperwork.) and they found the box that she was carrying.

There was a human heart in it.

She tries to convince them that she is a visitor by telling them her male friend watched her come in. But when she turned around he was gone.

She is put down as a patient.

The male friend is a demon who took partial control. He can't do anything unless she lets him- which she initially did during the riot. She gets mental shocked and decides to let him take control right before she gets shocked again.

She leaves and he shows her how to survive. She learns to kill and enjoys it. He helps her find her wild side.
