The Assassination Bureau

Aspiring journalist and women's rights campaigner Sonya Winter (Diana Rigg) discovers the Assassination Bureau Limited, an organization that kills for money, in 1908 London. She commissions the assassination of its chairman, Ivan Dragomiloff (Oliver Reed), but he turns the situation into a challenge for his board members: kill him or be killed. Dragomiloff goes on a globetrotting tour of Europe, challenging and systematically purging the bureau's senior members, including assassins in Paris, Zürich, Vienna, Venice, and a Zeppelin in Zurich, as he tries to stop the bureau from plunging Europe into war.
