Cass Chase loves her job running a dolphin show in a Los Angeles marina. Ever since she broke up with Australian Jack “Digger” Coady, her work has been her only life. Digger shared her passion for dolphins, and she can't imagine falling in love with someone who doesn't.
When they find each other six years later, their feelings are rekindled on sight, and Digger asks Cass to come to Australia for a month to see if they really are right for each other.
Cass falls in love with Digger's lifestyle and his tourist center with wild dolphins in remote Western Australia, but trouble surfaces when she suspects a local fisherman of dolphin poaching. Cass hatches a plan to catch him, but Digger thinks she's using the man to buy dolphins for her show. After he tells her he never wants to see her again, Cass is desperate and heartbroken.
Can their beloved dolphins help Cass and Digger find a future together?
