When a man comes to the station with a box containing a blood-stained dress with a bullet hole, Ali and Tony investigate a possible murder on the college campus in 1964. They discover the victim wasn't who she appeared to be.

Ali and Tony check out the story of an informant who claims he knows who killed a tow truck operator in 1991. Their case turns on the testimony of a woman who was a drug addict then, and who is now a hyper-religious housewife.
