Timofey Berezin (Paddy Considine) works at a former top-secret, badly run and aged nuclear reprocessing facility plant in Skotoprigonyevsk-16, a former closed city and a naukograd. At the film's outset, he is exposed to radioactive contamination while selflessly trying to prevent a critical malfunction. The facility's managers tell him that his exposure was a survivable 100 rems, while accusing him of sabotage and suspending him without pay. Loyal coworkers, however, help Timofey discover the truth that he was exposed to 1,000 rems of radiation. Suffering from acute radiation poisoning, he has only days to live.

Before Timofey's adoring wife, Marina (Radha Mitchell), is fully aware of his fate, he leaves for Moscow, on a mission to secure a better future for her and their young son. He hooks up with a small-time gangster, Shiv (Oscar Isaac), in hopes of finding a buyer for a selfmade canister of a little over 100 grams of weapons-grade plutonium salt he has stolen. It is 1995, only a few years after the dissolution of the Soviet Union, and they spend their time frequenting the hotels, nightclubs and private palaces of the new Moscow underworld, ricocheting between two rival crime lords (Nikolaj Lie Kaas and Steven Berkoff). However, what Timofey and Shiv never realize is that they are both caught in the same dilemma: trying to find a way free of a certain fate; hoping to do right by their loved ones before it is too late.
