The Successor (1996)

A young Englishman "Jason Connery" hounded by history, visits Russia to fulfil a promise made to his dying grandmother. He is embroiled unwittingly in the shadowy forces fighting for control of Russia: The Monarchists who desire a return to power for the remnants of the Romanov family, and the Neo-Communists, a shadowy, unscrupulous group that dabbles in trading plutonium.
