Overkill

S1 E19: As the birthday of Deaq's murdered older brother approaches, Van and Billie realize that Deaq is coping with painful memories. He tries to avoid the issue by focusing on the case against a ruthless drug lord. Meanwhile, NASCAR legend Dale Earnhardt Jr. (himself in a cameo appearance) accepts a street-racing challenge from the overconfident Van. Kristen Baker (wife of series star Bill Bellamy), guest stars as a flight attendant. Actor and director Bill Duke (star of "Exit Wounds," "American Gigolo," director of "Hoodlum") directed the episode.
