Reunited for the first time in over a decade, the sisters take a trip to spread their mother’s ashes at a secluded lake. As the sisters reconnect and try to heal old wounds, something waits in the nearby woods. A strange object, made not by the hands of man, beckons them to it. As they begin to try and unlock its secrets, Abby is plagued by nightmares of an alien presence that seem all too real. Little do the sisters realize that this object is actually a device, one with a purpose too horrible to comprehend.
