smile
At a psychiatric ward, therapist Dr. Rose Cotter meets with Laura Weaver, a graduate student. Weaver explains that she witnessed her art history professor commit suicide a few days earlier. Weaver then claims that an entity that only she can see, taking the form of smiling people, has been terrorizing her, and has told her that she is going to die, and nobody believed her when she told them. Soon after, Weaver stumbles to the floor and begins screaming. After Rose calls for help, she sees Laura standing up, calm and smiling. With a shard of broken pottery, Weaver kills herself by slitting her throat. Later, Rose sees a manic patient, Carl, smiling and shouting that she is going to die. Rose calls for nurses to restrain him, only to see he has been asleep the whole time. Concerned for Rose's mental well-being, her supervisor Dr. Morgan Desai gives her a week off.
