Kaori is a tomboyish teenager who spends her days roughhousing with her neighbors Ko and Yasu, two brothers living just down the street. Life in their quiet neighborhood follows a predictable rhythm until the morning a US military jet screams out of the sky and crashes nearby, shattering the peace of their ordinary world. The disaster forces the three friends to confront the fragility of their carefree existence and the unpredictable forces that can tear it apart in seconds. What begins as a day like any other becomes a turning point that will reshape how they see their families, their community, and each other. Based on a real incident that shook an entire city, the film captures how catastrophe arrives without warning and demands that young people grow up faster than they should. This is a story about the moment when childhood's safety net disappears and responsibility becomes unavoidable. It's intimate and grounded, focusing on how ordinary kids process extraordinary loss and learn to move forward.
