While staving off a power plant disaster, Russian worker Timofey (Paddy Considine) is exposed to radiation and blamed for the accident. With days to live, he steals some plutonium and tries to sell it on Moscow's black market in an effort to provide for his family. Along the way, he gets help from a low-level thug, with whom he forges an unlikely connection. Radha Mitchell co-stars in this gripping HBO adaptation of Ken Kalfus's short story.
