Someone's calling from the other side.
_____
On their rainy drive home from a haunted house tour in a small Pennsylvania town, sisters Megan and Dianne Willis come across a drenched, confused old woman walking alone in the middle of the road. Concerned about her well-being, the sisters attempt to take the mysterious lady to the nearest hospital to get checked out. However, their plan is quickly flipped upside down as the woman's suddenly violent behavior causes Megan to lose control of the car.
After surviving the crash and waking up in the middle of the woods with the woman nowhere in sight, Megan and Dianne traverse the dark, hoping to find help. But help won't come easy as the sisters soon discover they're isolated on the property of Shaded Grove Mental Hospital, where abandoned spirits roam, and all is not what it seems. It's up to Megan and Dianne to work with the ghosts of the past and the ever-changing environment before Shaded Grove traps them inside forever.
