In the 'Cuda, Joe reveals to Nash that his wife Inger is worried about Nash since Nash has broken up with Caitlin. Suddenly a slow car chase goes by. It's Nick learning how to drive. Nash finally pulls Nick over. At a liquor store, two thugs rob the store at gunpoint. A SFPD motorcycle cop runs in and shoots both thugs. The cop then proceeds with finishing the robbery by emptying the cash register.
The clerk has remembered the phony cop's badge number 1163. The owner of badge 1163 is Officer Jeff Roberts, but the clerk does not identify Roberts in a line-up and Roberts' alibi checks out.
The previous owner of badge 1163 is Tommy Krell, a heroic motorcycle cop shot to death during a routine stop. A check with Shelly, Tommy's partner, reveals that she mailed Tommy's badge to his mother in Minneapolis. But Tommy's mother died two weeks ago, and all her belongings were shipped to Tommy's brother Ray. The clerk positively identifies Ray as the phony cop, using his brother's uniform and badge.
Meanwhile, Ray has pulled over a woman for speeding. He agrees to let her off if she will have coffee with him. Suspecting something is wrong, the woman escapes at the restaurant. Ray has imaginary conversations with his dead brother, the ghost of Tommy. Ray goes to a robbery victim's house under the guise of investigating the crime, but Ray steals a pair of her panties. The SIU raids Ray's apartment, but he escapes because of advanced warning from his police scanner.
Nick is trying to get his own car to increase his independence, but Nick is an unsafe driver. Joe takes him driving, but instead Joe ends up locking bumpers with another car. Nick passes the written test, but finally fails the driving test. Meanwhile, Cassidy is again interested in Evan. Evan has paid off the debts on his repossessed truck. Evan coaches wayward boys, and she asks for help moving back to a Berkeley apartment. Evan arrives, only to deliver her moving crew. Evan must leave, much to Cassidy's disappointment.
The search of Ray's apartment reveals a shrine to Tommy, and Ray's panty fetish. The neighbor lady reveals that Ray did a lot of arguing with his brother. Security video from Ray's previous job as a security guard reveals Ray talking to himself. Meanwhile, Ray pulls over a wealthy couple and robs them. Ray pulls over a woman and two men leaving a nightclub. He sends the two men away, and pretends to offer to drive the woman home.
Her abandoned car is found the next morning. Harvey discovers her still alive in the trunk, shot, bound, and gagged. Nash and Joe arrive in the 'Cuda, suspecting that Ray has gone to the woman's house. Hot on Ray's trail, a hot pursuit ensues with the 'Cuda following the Kawasaki police motorcycle. Ray is cornered on the roof of a garage. His Tommy ghost tells him to jump, and Ray does, killing himself in a suicidal leap.
Nash and Nick are back in their apartment, consoling each other - Nash, for his recent break-up with Caitlin, and Nick for having failed to get his driver's license.
