Harry Exton, ex-mercenary, is a "Button Man", a hired killer pitted against other killers in an underground sport. Each works for a mysterious "Voice", a rich man of unknown identity. The object of the game is to kill your opponent, or capture him and take his marker - the first two joints of a finger. Button Men who lose three fingers are shot anyway. The "voices" profit from the game by gambling on the outcome, and a ruthless killer like Harry Exton can make a modestly wealthy man extremely rich. Exton decides to quit, only to discover that leaving the Button Man game isn't so easy.
