Korea's leading filmmaker, Kang Je-gyu, directed this epic-scale drama focusing on two brothers caught up in the madness of the war that tore their nation apart in the early '50s. Jin-seok Lee (Weon Bin) is a bright and well-educated young man whose older and more physically imposing brother Jin-tae Lee (Jang Dong-gun) believes he represents the best hope for his family's future. When both Jin-seok and Jin-tae are called up to fight in the South Korean army following the advance of Communist forces, a wary Jin-tae cuts a deal with his commanding officer -- if he racks up an impressive enough record on the battlefield, the army will give Jin-seok an early release. Jin-tae proves to be a fearless soldier, and is soon recognized as a war hero, but as the conflict wears on, he develops an unhealthy enthusiasm for the violence of the battlefield, and Jin-seok finds himself questioning his big brother's actions, both as a soldier and as a member of his family. The title Tae Guk Gi: The Brotherhood of War refers to the Korean name for the South Korean flag, originally designed in 1876 but outlawed during Japanese rule of the nation, and restored to use in 1948. ~ Mark Deming, All Movie Guide
