Heartbeat - Season 13 - Eps 1: Speed
Sgt Merton finds himself under pressure when a group of youths commit a number of serious offences in the area - and are suspected of drug-dealing when Liz Merrick hands in amphetamines found stashed in a local boy's bedroom. She refuses to reveal who passed on the drugs to her due to patient confidentiality rules, but Merton heads for the surgery regardless, pretending to see Jenny, who promptly calls off the wedding when she discovers her fiance used the visit to sneak a look at the patient list.
