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.

When a young woman claims to have a 17-year-old "recovered memory" of her sister's murder, the whole squad tries to sort through the family's secrets. Meanwhile, Ali attempts to get a confession from a terminally ill man long suspected of being a hit-man.
