Return of the Living Dead: Rave to the Grave

A student creates and sells a drug called 'Z' which has the unexpected side effect of resurrecting the dead as flesh-eating zombies, who proceed to wreak havoc at a Halloween rave. In this fifth installment of the Return of the Living Dead film series, the zombie apocalypse unfolds when people take too many pills containing the chemical "Z", causing them to reanimate and become undead. As the situation spirals out of control, a small group of survivors must navigate the chaos and try to find a way to stop the outbreak.
