This story is a fantasy about a family named Tuck who accidentally stumble upon a spring in a wood, which has the ability to give eternal life. They don’t realize at first what they have drunk until they realize that their bodies are not aging and they cannot be hurt or harmed in any way. They travel quietly around the countryside; never staying in one place too long so that people will not realize their secret. Into this family comes Winnie Foster, a little girl in search of freedom. She learns their secret and falls in love with them so deeply that she will do anything to protect them. The family and Winnie then must face a villain who would steal their secret for himself.
The movie is too impressed with its own solemn insights to work up much entertainment value; is too much fable to be convincing as life; is awkward in the way it tries to convince us Winnie's in danger when we're pretty sure she's not. Even its lesson is questionable. Is it better to live fully for a finite time than to be stuck in eternity? The injunction to live life fully need not come with a time limit. That's why the outcome of the romance is so unsatisfactory. I dare not reveal what happens, except to say that it need not happen, that the explanation for it is logically porous, and that many a young girl has sacrificed more for her love. Besides, just because you're 17 forever doesn't mean life loses all delight. You can get rid of that horse and carriage and buy a motorcycle.
