Years ago, Pierre Martin was convincted of murdering Randall Bettinger, but suddenly Bettinger turns up alive and well, making Len, who had busted the case, look very bad. Within 48 hours though, Bettinger is found dead for real, and Casey brings in both Nicco and Len to work the case, and each uses their snitches to help prove who murdered Bettinger. Mickey gets pulled in when the murder of 6-yr-old Jeannie Yan is reopened after nearly ten years, because the girl was the first dead child she ever saw. She asks Ali to investigate, and when Ali begs off, Mickey begins doing some detective work of her own.
