Traumatized since childhood by her brother's accidental death, Danika Merrick (Marisa Tomei) hallucinates a bank robbery and quits her job. Despite support from her three children and loving husband, Randy (Craig Bierko), Danika continues to experience unnerving visions. She seeks help from therapist Evelyn Harris (Regina Hall). But pervasive reports of violent incidents involving children make Danika fear for her own family, and she grows increasingly paranoid, worrying she may be going insane.
