In Ireland, the psychiatrist Jane Morton is assigned to give a psychological assessment to the disturbed teenager Dorothy Mills that tried to strangle a baby while babysitting him. After leaving the island ferry, an orange car with three teenagers causes an accident with Jane's car that falls in the sea and miraculously survives. She finds a hostile environment in the island with the unsettled dwellers that seems to be nervous with her presence. Jane seeks out Dorothy in the house of her Aunt Eileen MacMahon that is raising the girl and after a couple of interviews, she discovers that Dorothy has multiple personality disorder, impersonating the three year-old Mimi; and the teenagers Mary, Kurt and Duncan. When Dorothy embodies David, the young son of Jane that drowned in a tragic accident, the grieving psychiatrist also finds that the backward locals are fanatic religious believers and something dark lives in the island.—Claudio Carvalho, Rio de Janeiro, Brazil
