Catherine the Great delves into the politically tumultuous and sexually charged court of the most powerful female monarch in history. Catherine ruled all of Russia for almost half of the 18th century - resolute, independent, intelligent and sexually liberated, she was the definition of the modern woman. The miniseries follows Catherine towards the end of her reign and her passionate affair with Grigory Potemkin. Amid scandal, intrigue and immense conflict, this is a story of obsessive love. Unable to marry publicly and famously promiscuous, they develop a unique and committed relationship, overcoming their adversaries and together forming Russia as we know it today.
