Much to the dismay of the detectives at the 8th precinct, Jim's informant sets up a drug deal with Debbie Dyman, the girlfriend of his recently murdered second cousin. Sonny believes that this will help the police in their homicide investigation by giving them good leverage to apprehend and keep Debbie at the squad for questioning about his cousin's murder. The only problem with this deal is that he scheduled it to take place in a few hours with a blind man interested in purchasing the drugs.

After throwing out ideas and discussing other options, it is decided that Jim who is currently having a difficult time in his relationship with Christie will go undercover as the dealer with his colleagues positioned nearby to watch his back. Things don't go exactly as planned when Debbie finally arrives and reveals to Jim that she will be taking him to another location where the drugs are kept in an abandoned broken down locker. Tom and Marty attempt to follow Debbie's car, but are boxed in at the old location by a driver who parks his vehicle in their way.

At the new exchange location, Jim learns from Sonny and Debbie that the stored drugs are no longer in the locker as two unknown men approach them with weapons. They demand that the drugs be given to them, but the three are unable to comply with the request. So in retaliation, one of the men sucker punches Jim. Then the two take Debbie and Sonny hostage as they all drive off with Hank still in the car. With help from the rest of the squad, Jim attempts to find Hank as they collectively continue with the murder investigation. This whole situation proves troublesome for Jim as he worries about Hank, who is both a guide dog and trusted friend.
