Struggling actress Marin Keane is shocked when she lands a role in a major motion picture about the unsolved mystery of New Avalon, an island on sprawling Lake Faraday in Vermont. She’s even more surprised when she learns that the role requires a weeklong research trip to that very spot. A century ago, New Avalon was a commune for spiritual mediums --- until they all vanished in 1926. Not long after arriving, Marin and her castmates --- including legendary actress Violet Wright and white-hot director Ronan Peters --- begin to realize that all is not right with New Avalon. And after a sudden health emergency leaves Marin, Ronan and the other actors stranded on the island, the disappearances begin again.
