After enduring six grueling years in Russian prisoner-of-war camps during World War I, hundreds of Turkish soldiers finally begin their journey home on February 23, 1921. Boarding the Japanese ship Heimei-Maru, under the courageous command of Lieutenant Colonel Yukichi Tsumura, they believe their ordeal is over. However, as the ship reaches the waters off Mytilene, it is intercepted by a Greek warship, sparking a diplomatic crisis and a prolonged wait at sea. It isn't until June 25, 1922, that the weary soldiers finally touch the soil of Istanbul. Decades later, Mustafa Dokur, the son of one of those soldiers, embarks on a personal mission to piece together his father’s lost history. Armed with nothing but a faded photograph and a weathered notebook, Mustafa’s search for answers unearths a forgotten saga of resilience, international solidarity, and the unbreakable bond between a father and a son across time.
