剧情简介：Ben and his wife Jules are in for a surprise when they inherit an abandoned coastal property that Ben's recently deceased mother never told them about. Untouched for 40 years the house looms like an eerie relic over land which includes a stunning private cove and beach. The beauty and tranquility of the place leave the family with the nagging question: why was this property kept a secret for so long? While Jules rummages through the house looking for answers, Ben goes to repair the buried water tank, not knowing that in doing so he is unleashing a long-dormant creature, fiercely protective of its environment.
