Heartbeat: School of Hard Knocks

POVZETEK

No-nonsense teacher Jim Osgood uses his experience of the Territorial Army to impose strict discipline at Ashfordly School, but he goes too far with schoolboy trouble-maker Gary Bell and puts him in hospital. Determined to get revenge, the youngster breaks into Osgood's office and steals his gun, leaving Mason with little time to avert a tragedy. Joe McFadden and Lisa Kay star.
