The Unit is an action drama that follows a covert team of special forces operatives as they risk their lives on undercover missions around the globe, while their wives maintain the homefront, protecting their husbands' secrets. Jonas Blane leads the unit on missions out in the field and is responsible for taking elite new recruit Bob Brown under his wing. The Unit includes Jonas, Colonel Tom Ryan, Mack Gerhardt, Charles Grey, Hector Williams, and Bob Brown, all highly skilled soldiers, whose ability to rely on each other in life-threatening situations creates their unique brotherhood. Jonas' wife, Molly, is the base matriarch who comforts and counsels the other wives as they cope with the fear and uncertainty they experience when their husbands leave home. Molly and Tiffy Gerhardt, a wife hiding her own dark secrets, help Bob's pregnant wife, Kim, acclimate to the stress of her new secret life.
