What if the Fountain of Youth is real?
A 60-year-old virgin discovers the fountain of youth in her Miami backyard.
Lorelei, the 60-year-old virgin, is part-owner of a Miami lingerie shop. When her well runs dry, she hires Juan, a Cuban well-digger, who taps into a hidden underground spring. Lorelei attributes her increasingly youthful appearance to her obsessively healthy lifestyle, but her business partner, Sharleen, suspects that it's the water she's been drinking, and campaigns to sell it from the shop.
But someone else is interested in this water: Winona, a 500-year-old Native American woman who has lost the trail of the spring after following it through the ages. When she finds it again in Lorelei's backyard, she's desperate to claim it. The story evolves from there, linking Lorelei with Juan and Winona, and their connection to Ponce de Leon.
