Three homeless people find a baby on Christmas Eve and spend the next week chasing down impossible leads through Tokyo. What could be a sentimental rescue story becomes something rarer: a film that treats forgotten people like they matter, then proves it by making you care about their broken histories more than the plot. Satoshi Kon's animation doesn't just move, it observes, catching small gestures and city details that make these characters feel lived-in rather than drawn. The coincidences that bring them back to their pasts feel orchestrated at first, then inevitable, then necessary. By the end, you're not watching three people solve a mystery. You're watching three people save each other.

Three homeless drifters picking through garbage in Tokyo on Christmas Eve make an unexpected discovery: an abandoned baby girl. Instead of walking away, Gin, Miyuki, and Hana name her Kiyoko and set out to find her mother, working from a mysterious key and a note left with the child. What starts as a simple search unravels into something messier and more human, as a string of strange events throws their plans into chaos. Each person they meet and each clue they follow forces them to face their own troubled pasts. The film mixes comedy and drama as three people society overlooks stick together through the days leading up to the New Year, hoping to bring Kiyoko home and find a Christmas miracle of their own.
