New York Detective Ezekiel Stone returns from Hell to track down 113 escaped souls, a deal he made with the Devil for a second chance on earth. In the pilot episode, he crosses paths with a priest kidnapping children for a special purpose.
After refusing to join forces with an ancient Caraginian warrior, Stone races against time to save the lives of police officer widows while also being the primary suspect in the very case he's investigating.
While growing closer to Detective Ash, Stone hunts an arsonist who has been burning down places of worship only to discover it's someone closer to him than he could have possibly imagined.
Stone's mission, to send a damned soul infected with typhoid back to hell before she unleashes a terrible plague, is complicated after she infects him with her hellish disease.
