Every ten years, in an unsuspecting town, The Tournament takes place. A battle royale between 30 of the world's deadliest assassins. The last man standing receives the $10,000,000 cash prize and the title of World's No. 1 Assassin, which itself carries the legendary million dollar-a-bullet price tag.
