The beginning of a new school year ushers in unforeseen challenges for siblings Miles and Haley Miller as they adjust to significant changes in their lives. Their recently separated mother, Noelle, works relentlessly to support her family while adapting to their altered circumstances. Wanting to strengthen their sibling bond, Haley helps Miles navigate his romantic interests, but he soon faces public embarrassment. As tensions between the siblings escalate, Noelle becomes increasingly concerned by troubling shifts in Miles’s behavior—manifested through anger, withdrawal, and hostility toward her, Haley, and his peers at school. Following another painful rejection, Miles descends into the toxic realm of incels—a dark and hidden online community that intensifies his growing bitterness. As he sinks deeper into this dangerous mindset, Noelle and Haley race against time, determined to save him before he is completely consumed by darkness.
