Four strangers, Hikari, Ikuko, Ishi, and Takemura, met at a crematorium after the demise of their parents. While the orphans share the tragedy of traumatic accidents that killed their parents (suicide, explosions, etc.) they were unable to cry. Together, the four run away and create their own band, calling it “The Little Zombies.” The energetic, dark-humor laced film follows the teens as they navigate grief and meet various strangers who shape their mindset and future.
