Mandy Blythe is only scared of three things: water, boats, and planes. So she's not best pleased when her interfering boss tricks her into taking an Australian vacation in the company of the womanizing Damon Sutter, who's left a string of broken hearts across several continents. Damon just wants to explore the Great Barrier Reef and keep his association with Mandy strictly business. But the tropics are a different world, and paradise is only a heartbeat away.
