Four young men, fresh out of the academy and venturing into the world, embark on a perilous journey to uncover the truth, unravel the mystery of their origins, and become true gentlemen. They uphold the principles of gentlemanly conduct, demonstrating chivalry by "using their own strength to uphold justice." A remarkable book, a tale of love and hate, a belief, a legend.
