After an earthquake causes some damage to a nuclear power station, one of the chief nuclear physicists, Paul Brack, starts to investigate the safety procedures and policies of the station. He is dismayed to discover that there is a lack of real safety processes at the station, and quits his job in disgust. His disillusionment puts a strain on his relationship with his wife, Pat, a fellow researcher and academic.

Through a mutual friend, Brack meets and begins to work for energy consultant Harold Harlan, with hopes that Harlan can highlight the issue of nuclear safety, and explore alternative energy sources. Unfortunately Harlan has his own plans for how he can use Brack.
