Synopsis：Set in late 20th-century Belfast, this story follows the Raphael family as they move into a new suburban home, only to be confronted by a series of unsettling events. It begins when the eldest daughter, Ellen, is the only one who can hear the creaking of a rocking chair in her room. Her parents dismiss it as imagination, but things take a darker turn when she discovers a music box and a bloodstained note covered in strange symbols hidden beneath her floorboards. Disturbed, she confides in her younger sister, Elsie, who reveals that she has been seeing a young boy, about her age, playing in the garden every night. Determined to uncover the truth, the sisters investigate the history of No. 16 St. Heaven Street, and learn of a previous family who were mysteriously murdered there, in a case that was never solved. As the past bleeds into the present, Elsie suddenly disappears without a trace. With their daughter missing and the house’s secrets closing in, Mr. Raphael and his wife Eva can no longer deny that something deeply sinister is lurking within their new home.
