Heartbeat

Rob is forced to confront his criminal past when he undertakes his own unofficial investigation into a series of violent burglaries against the elderly residents of Aidensfield, but his snooping into the lives of his father's dangerous associates looks set to have a profound impact on the officer's family when he finds evidence that could nail a major underworld figure for an unsolved armed robbery, which would also put his own father behind bars. Meanwhile, David falls for Matthew Trent's former mistress and finds himself acting as a secret messenger in their sordid affair, leaving Gina, Bernie and Rosie suspicious of his behaviour. Elsewhere, a fresh new constable shows up at Ashfordly station for his first day - PC Geoff Younger, much to the man-eating sergeant Nokes' delight.
