Blackout follows Daniel Demoys (Christopher Eccleston), a stranger in his own life. Over the years he has gone from being an idealistic young man with a burning desire to make the world a better place, to a disillusioned and corrupt council official. His alcoholism has driven a wedge between him and wife, Alex (Kirwan), and their three children. The fallout from his alcohol fuelled actions prove agonising for all around him.
