Milton, a hardened criminal, escapes from Hell to rescue his baby granddaughter from a cult led by the vicious Jonah King. King, a deranged and fanatical leader, believes sacrificing the child during a full moon will unleash Hell on Earth. Determined to stop the cult and save his granddaughter, Milton races against time and is relentlessly pursued by the Accountant, a demonic operative sent to drag him back to Hell.

Along his journey, Milton teams up with Piper, a strong-willed waitress who becomes embroiled in his mission after a violent encounter with her abusive fiancé. Together, they face brutal confrontations with King's henchmen, high-speed chases, and supernatural battles. Each encounter escalates in intensity as they draw closer to the cult's ritual site, fighting against increasingly dangerous odds to thwart King's apocalyptic plan.
