Charlie feels like she's always coming in last. From her Mom's new job to her sister's life at college, everything seems more important than Charlie. Then one day while ice fishing, Charlie makes a discovery that will change everything . . . in the form of a floppy fish offering to grant a wish in exchange for freedom. Charlie can't believe her luck but soon realizes that this fish has a very odd way of granting wishes as even her best intentions go awry. But when her family faces a challenge bigger than any they've ever experienced, Charlie wonders if some things might be too important to risk on a wish fish.
