Stop-motion doesn't move like this anymore. Every frame feels handmade, deliberate, alive in a way that digital animation struggles to touch. The well isn't a portal, it's a test, and the movie knows that kindness rewarded and cruelty punished works because it never pretends to be anything smarter than that. One sister descends curious and returns changed. The other descends bitter and never makes it back. That's not a moral lesson delivered, that's a world with rules, and the movie trusts you to see what happens when you break them.
Two sisters share the household chores. One of them falls into a well while trying to get back a pail and is carried off to a wonderland full of strange creatures. She helps the creatures she meets, and they reward her for it. When she comes home, her sister grows jealous and tries to follow the same path. Once there, she is rude to everyone and, out of selfishness, helps no one. Told in stop-motion animation, this fantasy film sets kindness against selfishness through the two sisters' journeys.
