Based on a film by the creators of the Japanese version of “The Ring” comes this haunting, chilling film about a young mother who goes to extreme lengths to solve a mystery and protect her daughter. Dahlia Williams (Connelly) is starting a new life; newly separated with a new job and a new apartment, she’s determined to put her relationship with her estranged husband behind her and devote herself to raising her daughter, Ceci. But when the strained separation disintegrates into a bitter custody battle, her situation takes a turn for the worse. Her new apartment – dilapidated, cramped, and worn – seems to take on a life of its own. Mysterious noises, persistent leaks of dark water, and strange happenings cause her imagination to run wild, sending her on a puzzling and mystifying pursuit to find out who is behind the endless mind games. As Dahlia frantically searches for the links between the riddles, the dark water seems to close around her. But one thing trumps all others in Dahlia’s world: no matter what it is that’s out there, she’ll stop at nothing to find it.
