Something lives behind the door.

When Janie's boyfriend Mark goes missing while filming a ghost hunting documentary, she spirals into a deep depression. Three months pass with no leads or answers.

With all hope fading and facing the reality of a future without him, Janie receives a package in the mail with no return address. It contains a flash drive and a simple note...

Mark is not dead. I need your help. Watch the videos.

The truth is more sinister than she imagined. She shares the videos with Mark's sister Leslie, and together they are pulled into a mystery that changes everything.

Sometimes the missing should not be found.
