Russia, 1986. In a run-down apartment block in Moscow, a nine-year-old piano prodigy practices silently. In the hospital, a surgeon immerses himself in his work to avoid facing his failed marriage. And in a rural village in Belarus, a teenage boy wakes up to a sky of the deepest crimson. Outside, the ears of his neighbour's cattle are dripping blood. Ten miles away, at the Chernobyl Power Plant, something unimaginable has happened. Now their lives will change forever.
