Okinawa, 1945. San and Mayu, two ordinary schoolgirls, find their lives irrevocably altered as the Pacific War reaches their shores.

Their bonds of friendship are tested to their limits as they navigate a landscape of devastation. Cocoon portrays a harrowing journey of resilience, loyalty, and the enduring hope for a future amidst the ruins of war.
