S3 E7: When an unidentified man is found shot and sexually abused in the alley outside of a gay bar, Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) search for possible motives and suspects, tracing the victim's (guest star Mark-Paul Gosselaar) history back to a small town in Arkansas. However, when their investigation leads the detectives deep inside the porn industry, they realize it is not a clear-cut case of rape and attempted murder.
