Road to Boston

In the 1936 Berlin Olympics, marathon gold medalist Sohn Kee-chung set a world record. On the podium, as Japan's national anthem "Kimigayo" played, he covered the Japanese flag on his uniform with a potted plant. Overnight, he became a national hero to Koreans, but under Japanese colonial rule, he was forbidden to run again.

In 1947, post-liberation Seoul, rising star Suh Yun-bok is seen as the second Sohn Kee-chung. Suh is suddenly approached by the legendary runner himself, who suggests they compete in the Boston Marathon. Sohn wants to reclaim the glory lost in Berlin, this time running proudly under the Korean flag. Though they couldn't even afford a single pair of running shoes, the Korean marathoners embark on an unforgettable journey to Boston.
