Memories of the Sword (2015)
Three warriors from the Goryo Dynasty, Poong Chun, Deok Ki, and Seol Rang, lead a riot for the impoverished. After Deok Ki betrays them, Poong Chun dies, and Seol Rang, guilt-ridden, flees with his sword and infant daughter, Hong Yi.
Eighteen years later, Seol Rang, now blind, trains Hong Yi in martial arts. Seol Rang eventually reveals she killed Hong Yi’s parents, leading the young woman to seek revenge on both her and Deok Ki, now the most powerful man in the country. Blood will soon be shed.
