Dave Quinnan arrives late after rowing with Jenny all night. Ever the troublemaker, Sgt. Boyden sends him out on patrol with Polly Page, Tony Stamp and Vicky Hagen. Quinnan and Page have trouble keeping their mind on the job, and this gets dangerous when Stamp is attacked by a gang of thugs on the DLR and Quinnan is nowhere to be seen. When Jenny leaves him and returns to Dublin, Dave starts to crack up. He puts on his uniform after his shift and goes on a vigilante mission to find the gang responsible for the attack on Stamp. DC Webb gets an anonymous call and finds some of the gang members tied up and sprayed with pepper spray. (thetvdb.com)
