On april 26, 1986, the chernobyl nuclear power plant in ukrainian ssr suffered a massive explosion that released radioactive material across belarus, russia and ukraine and as far as scandinavia and western europe. Dramatising the true story of the 1986 nuclear accident, one of the worst man made catastrophes in history, chernobyl shines a light on the brave men and women who fought an unprecedented war against an invisible enemy, and who suffered and sacrificed, saving millions of lives, often at the cost of their own.
