Deputy Chief Brenda Leigh Johnson and her staff investigate the murder and dismemberment of Chris Mundy, who, it turns out, is a major porn star. Initially, they only have his head and feet, but it's more than enough to confirm his identity through dental records. It's also enough to confirm that he was HIV positive, both a surprise and a problem given his profession. The porn industry requires all actors to be tested regularly, and Brenda suspects he may have been hiding his HIV status. His wife Annalisa, for one, refuses to believe it, and it becomes entirely possible that someone to whom he passed the virus may have sought revenge; however, the real solution is far more complicated. Meanwhile, Sgt. Gabriel informs Brenda that he and Det. Daniels are now dating.
