The government is pursuing a nuclear deterrent at breakneck speed and pinning its faith in that to prevent another conflict. They push the project too hard and there is a catastrophic reactor fire. This must never be public knowledge so a cover-up starts that must last for years and keep the scores of people who know what happened silent.
Those charged with the cover-up go too far; they have instilled fear but now they have to cover up their own actions. One man knows way too much and is suspected of having hard evidence. How far will they go to keep him silent and protect their careers?
