There's the damaged but driven Detective Louis Fitch, a wily homicide vet who is the most respected -- and most misunderstood -- man in the division; Detective Damon Washington, Fitch's new partner, who finds the first day on the job is a trial by fire, complicated by the imminent birth of his first child; Detective Ariana Sanchez, sexy, edgy and beautiful, who has emerged from a rough background to become a rising star in the department; narcotics undercover cop John Stone, a streetwise smooth talker, clever and quick with a smile made for the movies, who is teamed with Sanchez -- a combustible pairing rife with conflict and sexual tension; Sergeant Jesse Longford, a 30-year veteran and sage of the department struggling with his impending retirement from the force and the city he loves, who, together with his partner, Detective Vikram Mahajan -- a fully Americanized son of Indian immigrants -- form an amusing mismatch of experience and enthusiasm, intellect and instinct, old school and new world, but whose combined skills have never encountered a case that couldn't be cleared; and all are headed by Lieutenant Maureen Mason, a strong-willed single mom struggling to balance home and work. The unit works with the primary medical examiner, Dr. Abbey Ward, who has an unusual hobby in her off-hours roller derby.
In the premiere episode, "Pilot," Detectives Washington and Fitch investigate a double homicide at a pharmacy. Was it a drug theft gone bad or something else entirely? Meanwhile, Longford and Mahajan try to track down the killer of an attorney with many enemies. When both cases intersect, the cops are in a race against time to stop the killing spree, culminating in a high-speed pursuit and a perilous standoff, putting the cops in harm's way.
The men and women of Detroit Homicide are as smart and tough as they come. They have to be, as they struggle with their own inner demons, using only their sharp sense of humor to keep them grounded while working the neighborhoods of the historic Motor City.
