Mike and Carl's friendship has fallen apart since the previous episode. Mike is forced to work with his new partner, who follows the rules by the book, but working with his new partner is proven to be quite difficult for him after he accidentally shoots off his rifle and he destroys the roof of the police cruiser. Carl decides to take Mike back as his partner despite the ups and downs they have gone through. Meanwhile, Molly and Peggy participate in a NPR interview.
