S16·E11 On The Wagon

PC Jim Carver returns to duty after undergoing treatment for his alcoholism. Unfortunately for him, he is paired with PC Dale Smith and their first case involves alcohol! Attending what first appears to be a racial assault at a post office, Carver uncovers a scam to sell thousands of pounds worth of illegally imported alcohol to off-licenses. Smith and much of the relief don't trust him, and after a Customs raid on a off-license which turns out to be an empty building, Carver must go out on his own (and on his own bicycle!) to find the person behind the scam.
