The film had its world premiere at the Los Angeles Film Festival on June 8, 2016, and was released in the United States and Canada on July 22, 2016 by Warner Bros. The film has grossed over $148 million and received generally positive critical reviews.
In a textiles warehouse, Esther (Lotta Losten) sees a silhouette of a woman with monstrously long fingers when she turns the lights off, but sees nothing when the lights are on. She warns owner Paul (Billy Burke) about the apparition and leaves. Paul is later dragged into the darkness and gruesomely killed by the woman.
Paul's stepdaughter Rebecca (Teresa Palmer) lives alone in an apartment, away from her mother, Sophie (Maria Bello), and brother, Martin (Gabriel Bateman). Sophie has a mental illness and depression that has resurfaced, in which she talks to an apparently imaginary "friend." When Martin sees the apparition with his mom, his fear gives him insomnia.
Because he has been falling asleep in class, his teacher Emma (Andi Osho) calls Rebecca to the school. Rebecca takes Martin home, but after a fight with their mother, she takes him to her apartment to protect him. That night, she awakens to scratching by the silhouetted woman - who almost attacks her -, though Rebecca manages to turn the light on, making the figure disappear. The next morning, Rebecca finds what the woman was scratching into her floor: the name "Diana." She recalls her experiences with Diana from her own childhood, and the reason she left when her father abandoned them.
That night, Sophie has a movie night with Martin, but includes her imaginary friend, frightening him. She tells him a story about Diana (Alicia Vela-Bailey), a friend she had when she was in a mental institution for her depression. Diana had an unusual condition that made her skin light-sensitive. Martin looks up to see Diana crouched above him and runs to turn on the light, and Diana throws Sophie out of the way to get to Martin. She fails and Martin escapes to Rebecca's.
Rebecca confronts Sophie about Diana but she denies the accusation. Rebecca, her lover Bret (Alexander DiPersia), and Martin decide to stay overnight to protect Sophie. Rebecca goes to her mom's bedroom door to reconcile when Sophie secretly passes her a note saying "I need help", before Diana tugs her back into the darkness. Rebecca realizes that her mother is being controlled by Diana, and turns on all the lights in the house to keep her away.
Knowing their intentions, Diana baits Rebecca and Martin into the basement by turning off all the lights. Bret is attacked but escapes and contacts the police. Rebecca realizes that while Diana disappears under normal light conditions, the use of a black light can allow them to see her. She discovers scrawled writings along a basement wall, explaining how Diana will not let anyone take Sophie. Diana reveals that she killed Rebecca's father, and that he didn't abandon them.
A pair of police officers arrive to help and are promptly killed by Diana. Rebecca sends Martin outside to Bret, and goes back inside to rescue her mother. Diana is about to kill Rebecca when Sophie arrives brandishing a pistol. Sophie exclaims that she's the only connection Diana has that tethers her to the human world. She sacrifices herself with a bullet to the head in an effort to save her children, causing Diana to burn away and disappear.
Afterwards, the police carry away Sophie's body, with the distraught Rebecca, Martin, and Bret at the ambulance, as they embrace and vow to stay together. The lights in the ambulance momentarily flicker, but Bret dismisses it, to Rebecca and Martin's relief.
