Sparks fly when Molly Prince's puppy Ursula constantly disrupts the beachfront area where new-in-town marine biologist Max Miller is studying sea-turtle mating habits. Max and Molly are instantly attracted to each other, but Molly dismisses Max out of hand. She's not dating anymore-maybe not ever, since her last relationship ended in a spectacular disaster. As for Max, he refuses to take Molly seriously when her job is to play pretend as the aquarium's mermaid. But when Ursula won't stop digging in Max's beachfront yard and reveals her unique ability to sniff out sea-turtle nests, she might bring these two opposites close enough to help save the turtles, and maybe even save the aquarium...
