Meet a new cast of characters-homicide detective Peter Katzmark; the newest covert operative Roberta Finchum; recently promoted Computer Forensic Specialist Julie Walters; upcoming Agency star Cathy Chapin; FBI Agent Theresa Gall; with Winstead, the Lone Wolf's main go-to-guy. Watch as The Lone Wolf does everything in his power to protect his grandson.

Get reacquainted with the Korean based Team led by Director Nena Valdez, and team members X.O.
