Donna, an up-and-coming executive, tears herself away from work—but not her laptop—to join her sister on a summer cruise in the Adriatic Sea. The trip is a big step for Karen, whose husband booked the voyage just before his sudden death a year ago.

Karen warns her forever-single sister that Donna won't find love on this ship. That's fine with her since her focus is keeping her sister happy, while sneaking in a bit of business in her off-hours and trying to hide her fear of water.

Scottie, an officer on the ship, has to keep out of trouble after a recent fling with the bottle nearly cost him his job. Even though consorting with a passenger could threaten his own future, he can't resist the lively, phobia-stricken workaholic.

It's never hopeless to be a romantic, is it?
