When a boy named Jimmy tries to retrieve his football from the roof of the Carlingham Alloys factory, he collapses and later dies in hospital. An inquest reveals that his lungs burnt out as a result of Beryllium poisoning. The highly unusual circumstances of Jimmy's death leads to Doomwatch investigating the factory, where a new alloy process is being developed. Then one of the workers named Nicholls dies from a high fall after also getting Beryllium poisoning. Quist then starts making health and safety recommendations for the factory costing many thousands of pounds, causing the International company to shut their Carlingham factory down and move production to their Leicester factory, much to the locals disagreement and anger. Both management and the workforce become increasingly angry about the Doomwatch investigation, which they see as a threat to their profits, ambitions, expansion plans and jobs.
