It's based on a book, actually. It's about a family (the Tucks) who drinks from a spring that gives them everlasting life, and nothing can harm them. They live deep in the woods that belong to a snobby, rich family. One day, when the family's daughter's out for a walk in the forest, the Tucks kidnap her and bring her back to their house. So yea...the girl falls in love with the Tucks' younger son, Jesse, and a bunch of stuff happens.
I just love it for the love story in it. 😉
