Apocalypse 99

Nuclear power and naked ambition are the recipe for disaster when Vladimir Samailov, director of a Russian powerplant, overrules his safety director, Vladimir Mentschov, who knows the place is a timebomb. And to ensure he stays quiet Samailov has him fired.
Mentschov′s successor, Oleg Gusenko, is just as critical but Samailov
continues to put career before conscience. So Mentschov, slowly losing
his grip on sanity, manipulates the cooling system to make the reactor
overheat and so prove the safety valves will fail.
As
news of what he′s done spreads among the population like wildfire, Oleg
and his wife Larissa, of whom Mentschov is very fond, try to reason
with him. But the very safety problems Mentschov is trying to highlight
mean he can′t reverse his actions. Racing towards disaster, they all
struggle to prevent the looming catastrophe.
