Boston 1947 (2023)

Ki Jung won the gold medal at the 1936 Berlin Olympics, but because Korea was under Japanese colonial rule at the time, he wore the Japanese flag on his chest.
In 1947, two years after Korea’s liberation from Japanese colonial rule, Seo Yoon Bok is a 24-year-old marathon runner. He prepares for the upcoming 51st Boston Marathon with Head Coach Son Ki Jung and Coach Nam Seung Yong. Running the tricky and tough 42.2-kilometer course in Boston requires intensive training and patience. However, winning was not the only goal for Korean marathoner Seo Yoon Bok and his coach, Son Ki Jung, at the 1947 Boston Marathon. Ki Jung badly wants Yoon Bok to win while wearing the Korean flag on his chest.
