Cardinal is a Canadian crime drama television series, which was first broadcast on January 25, 2017, on CTV (in English) and Super Écran (in French). The series adapts the novels of crime writer Giles Blunt, focusing on police detective John Cardinal (Billy Campbell) and his partner Lise Delorme (Karine Vanasse), who investigate crimes in the fictional city of Algonquin Bay.
John Cardinal (Billy Campbell) is a troubled and brooding police officer in Algonquin Bay, who was removed from the homicide squad as a result of chief Noelle Dyson's (Kristen Thomson) belief that he had become obsessed with his investigation of a missing Native Canadian girl. When the girl's body finally turns up, he is reassigned to the case with new partner Lise Delorme (Karine Vanasse); what he does not know is that Delorme is being assigned to investigate him, as part of a federal police corruption probe which has identified Cardinal as possibly collaborating with a local drug dealer who has repeatedly managed to elude arrest. The investigation widens when another missing person case with some similar patterns leads Cardinal to believe that a serial killer may be active in the area.
