A sober schoolteacher named Nat Cullen and his wife Doris settle into his family's abandoned mansion atop a Maine peak for the summer, but strange behavior soon overtakes him—old-fashioned speech, vivid dreams of piracy, and unsettling sleepwalking episodes that lead him to a specific spot where the locals are building a new road. As Nat's personality shifts and his grip on reality seems to slip, Doris grows increasingly alarmed, wondering what force the decaying old house and Nat's mysterious seafaring ancestor may have awakened.
