Sam, fueled by her obsession with the deaths of those close to her, researches ways to contact the dead. She stumbles down a dark internet path, finding a message board with users discussing a house in the mountains that supposedly has some connection to the afterlife. However, no one who has visited the house has ever returned. Left with seemingly no other option as her obsession consumes her, Sam seeks out the house to find out for herself - no matter the consequence.
