This season's six-part, one-hour drama series will be directed by Adrienne Mitchell and Charles Binamé. It features returning stars Hugh Dillon as Detective Mike Sweeney, Hélène Joy, Laurence Leboeuf and Greyston Holt. Joining the team is new cast member Michael Nardone as Detective Ivan Sujic.

In the third season, Detective Sweeney’s new task force investigates the brutal murder of two young boys along the 401 highway corridor, while one of their own officers struggles to bury a dangerous secret. Meanwhile Audrey and Sadie embark on a new chapter of their lives and Mike must push himself beyond his limits to overcome a sudden tragedy that may tear his family apart forever.

“The Durham County franchise is being recognized from New York to Paris to Sydney as establishing a new standard of dramatic excellence in television," said Executive Producer Michael Prupas (Human Trafficking, Ben Hur). “The 3rd season will build an even broader audience as it delves into the mind and memory of a military man who has witnessed the worst of human behaviour."

"In the 3rd season we're looking at the kind of violence that's sanctioned by the community. Our antagonist is a former soldier and the action takes place in a Durham that's imagined as a war zone,” added Writer-Executive Producer-Co-Creator Laurie Finstad Knizhnik.

"Michael Nardone, who plays Mike's nemesis, Ivan, in season 3, has an incredible authenticity to him that stems from his life growing up battling gangs in the tough town of Fife , Scotland . He brings both a fierceness and compassion to a very deeply disturbed character. The chemistry between him and Hugh is spellbinding to watch," said Director-Executive Producer-Co-Creator, drienne Mitchell.

"This season the Sweeney's are all entering a new and exciting phase in their lives," said Janis Lundman, Executive Producer and Co-Creator. "But everything begins to spiral out of control and their lives will be turned upside down. It’s going to be a terrifying but wonderful ride.”
