T. J. Hooker (1982)

Season 5: Episode 4

A 17-year-old girl is killed in a struggle during the filming of a porn movie, and when her dumped body is found, it turns out to be the niece of Hooker's colleague, Detective Max Brodsky. Hooker takes charge of the case, with Stacy going undercover as a potential porn star to get inside the production company; but Brodsky's obsession with nailing the killers himself jeopardises the whole investigation.
