In the chilling horror-comedy Deadtention, a group of high school students finds themselves trapped in detention on Halloween night, faced with an unexpected and terrifying twist. As they navigate the claustrophobic confines of their classroom, the diverse cast of characters—each with their own secrets and agendas—must confront their personal demons while battling an unseen malevolent force that begins to prey on their fears.

Among them is the overachiever, determined to use detention as a stepping stone for academic success; the rebellious slacker, who views this punishment as an opportunity for mischief; and the social outcast, who struggles to find common ground with her peers. Their conflicting personalities fuel tension, but as the terror escalates, they must set aside their differences to uncover the truth behind the sinister occurrences haunting them.

With a clever blend of humor and suspense, Deadtention explores themes of friendship, betrayal, and the pressures of adolescence, all while keeping viewers on edge. As the clock ticks down, the stakes rise, and the students must find a way to escape both the detention room and the dark forces that threaten to consume them.
