One Hour to Zero 1976

In the fictional Welsh village of Llynfawr, Steve, [Toby Bridge], runs away from home after an argument with his father. His sister Maureen Rogers, [Jayne Collins], enlists the help of Paul Jenkins, [Andrew Ashby], to find him, though Paul is initially unwilling. He eventually locates Steve in an abandoned slate quarry. On their return they find the village deserted and are unaware that the village has been evacuated because of the danger of an incident at a nearby power station. They are unable to contact the outside world as the village’s only public telephone was vandalised by Steve in an attempt to get money from it. While searching the village they stumble across Mike Ellis, [Dudley Sutton], robbing the local cash and carry, and Paul Jenkins is locked in the quarry as Mike escapes. Steve tries to free him but fails; Paul Jenkins’s father, [John Barcroft], arrives. The two children are still missing as Steve’s father, [John Forgeham], returns to his place of work—the power station—to correct the cooling fault and prevent the disaster. He eventually succeeds with seconds to spare, and is reunited with his son.
