Time Bomb

A saboteur sabotages a trainload of sea mines destined for the Royal Navy Yard at Portsmouth. The train is stopped as soon as possible in case an explosion is imminent, but a residential area is nearby and the police have to evacuate local residents. A former World War Two Royal Canadian Engineers bomb disposal Major Peter Lyncort (Glenn Ford) disarms a bomb. A second bomb is due to go off at any moment, killing them all and devastating the neighbourhood.
