In "Detroit 187" (ABC), a documentary crew rolls with some of Detroit's finest. There's the damaged but driven Detective Joseph Fitch (Michael Imperioli), a wily homicide vet who is the most respected - and misunderstood - man in the division. His new partner is Detective Damon Washington (Jon Michael Hill), who in addition to the pressure of his first day working Homicide is also expecting his first baby. Then there's sexy, edgy Detective Ariana Sanchez (Natalie Martinez), who has emerged from a rough background to become a rising star in the department. Detective Sanchez has recently been teamed with the streetwise, smooth talking Detective John Stone (D.J. Cotrona) - a combustible pairing rife with conflict and sexual tension. Headed by strong-willed single mom Lieutenant Maureen Mason (Aisha Hinds), the men and women of Detroit Homicide are as tough as they come.
