A boy and a sea turtle become witnesses to each other's endings. This is not a story about heroism or grand sacrifice, it is about the small, devastating kindness of two creatures who cannot save the world, only each other for a moment. War takes everything, even the chance to say goodbye properly, so this film makes you feel the weight of what silence means when words run out.

Umigame to Shounen is a 2002 television special and the first entry in Sensou Douwa, a line of war stories that Shin-Ei produced each year for children. Every film in the line takes the Second World War as its theme. As a one-episode drama, it opened the annual series for a young audience.
