Ten year-old Jessica lives near the beach with her mother and few friends. She dreams of her father whom she's never seen. One day she finds a pretty stone on the beach, that, when picked up, starts telling her a story about love. She tries to convince her mother and friends she's found a special stone, but all think she's pretty much gone mad.
The stone, which claims to be the heart of an old pirate, helps her get connected to reality again, and accept the fact that her father is not the man of her dreams, and that her mother and friends is all she's got.
