camera has the initials "RJS" carved into it. Bird snaps a picture of Tyler but later notices an odd smudge-like figure on his photo. Bird attends a costume party with her best friend Kasey and meets her other friends Mina, Mina's boyfriend Devin, Avery, and Bird's high school crush Connor. She uses her Polaroid camera to take the group's picture and Avery later snaps a selfie with it. Meanwhile, Tyler is killed by the entity, and Sheriff Pembroke informs Bird. At home, Bird sees Tyler's photo free from the shadow, which has mysteriously transferred to Avery's photo. Avery is killed when the entity snaps her neck.

Devin finds Mina's dead body and blames Bird for her death. Bird and Connor research and discover that the camera was owned by a photography teacher Roland Joseph Sable (RJS) from their school years ago. He was accused of torturing four students and killing three of them while taking maniacal photographs. One of the captives escaped and Roland was killed by police. Devin confronts Bird at the diner and accuses her of being responsible for what happened to Mina. He attempts to take a picture of her as a threat. With Connor and Devin both fighting for the camera, Devin is accidentally snapped by the camera and the shadow transfers to his photo, showing he is next. Devin lunges at Bird, Kasey saves Bird by stabbing Devin's photo with a pencil, injuring him in real life. Devin, upset from being stabbed, becomes aggressive and accidentally
