The Assassination Bureau was founded by the father of Ivan Dragomiloff (Oliver Reed) to rid the world of people the world needed to be rid of. You know the sort, tyrants and such. Now the Bureau's lost sight of its lofty beginnings and become pretty much just a murder-for-hire business. So Sonia Winter (Diana Rigg) hires Dragomiloff to assassinate himself. He accepts. (See the clip embedded below.) But while he does think it would be a fine idea to but an end to the Bureau, he doesn't really plan to have himself killed. Instead, he issues a challenge to the employees: Kill me before I kill you. And we're off on a rop around Europe as Dragomiloff, with Winter along, too, of course, begins to wipe out the members of the Bureau.
There's lots of great scenery, a good bit of suspense, lots of clever stuff, and a big ending with a zeppelin. It's all a lot of fun if you're in the right mood. Check it out.
