Set in and around Memphis during the early 1970s, Season 1 of this thrilling action-drama series centers on Mac Conway, a Marine who returns home from a second tour of duty in Vietnam, only to find himself stigmatized by his involvement in a highly publicized massacre while fighting abroad. Though he and fellow Marine Arthur Solomon have been exonerated of wrongdoing, they are greeted with hostility and rejection in Memphis, with neither able to land a decent job. With Mac's relationship with his wife Joni growing tenuous, he and Arthur are tempted by a lucrative offer from The Broker, a shady criminal involved in a network of killing and corruption that spans the length of the Mississippi River. At first, Mac refuses to offer up his services to The Broker, but after Arthur opts to trade his principles for quick cash, Mac - whom The Broker codenames 'Quarry' - finds himself conscripted against his better judgment into The Broker's crew, a turn of events that has dire consequences for both himself and Joni.
