Due to certain irreconcilable differences two Scottish men, one being Catholic and the other being atheist, decide to fight a duel to the death. However, duels are against the law, so they have to find a secret place for that occasion. Searching for such place they must avoid authorities, and also numerous kinds of people who all try to convince them to give up on a duel, leading to many comic adventures.

G. K. Chesterton (1874-1936) was an English writer, poet, philosopher, dramatist, journalist, orator, lay theologian, biographer, and literary and art critic. Chesterton is well known for his fictional priest-detective Father Brown, and for his reasoned apologetics. Even some of those who disagree with him have recognized the wide appeal of such works as Orthodoxy and The Everlasting Man. Chesterton is often referred to as the "prince of paradox".
