An attorney for a large chemical company comes to the twelfth precinct to ask for assistance in identifying the person who has been vandalizing their properties. Wojo brings in a homeless woman who was the victim of a mugging so she could fill out a report.

As Wojo anxiously awaits the results of his sergeant's exam, Harris laments not being able to find a suitable apartment to move into. Thanks to the bright idea of Yemana, the detectives try using a tv guide to figure out where a copy cat criminal will strike next, based on what will be on television for the upcoming week. Harris brings in a drunk when he attempts to rob a liquor store without the use of a weapon.
