The story begins in March 2018, when former Russian intelligence officer Sergei Skripal and his daughter Yulia collapse on a park bench in Salisbury, England – a quaint, historic city where nothing normally happens. But what starts as a local incident explodes into a geopolitical crisis, which exposes the covert espionage war being raged between Russia and the West. A cinematic portrait of loyalty and betrayal and a story that resonates amid ongoing tensions with Russia, the documentary explores the collision of two men: Sergei Skripal and Vladimir Putin, the dictator determined to settle an old score by sending assassins to Salisbury armed with the deadly nerve agent Novichok.
