Here's what happens:
* Winnie Foster, the protagonist, is exploring the woods near her home.
* She stumbles upon a strange, almost magical place with a peculiar spring and an old, weathered well.
* While exploring, she encounters the Tuck family, who are drinking from the spring.
* The Tuck family reveals that the spring holds a secret: it grants eternal life to those who drink from it.
