Did he want to marry her—or murder her?
All Maggie Faribault's resources have gone into Pontoon, a women’s beach & boat boutique. It's going broke. To escape the coming collapse of her enterprise, Maggie accepts an invitation from her ex to spend a weekend on his yacht with his new girlfriend and a friend. On the boat, she meets Trevor Nelson, an Australian working part-time for the harbormaster’s office. They’re attracted to each other but their newfound romance is curtailed when, on the trip back, Maggie sees bodies floating in the sea. No accidents; they’ve been shot.
The deaths are attributed to a gang illegally smuggling immigrants. It makes the news, and Maggie’s interviewed. Soon afterward, those responsible for the killings make Maggie their next target, and her life becomes that of a hunted animal. Maggie longs to turn to Trevor for shelter, but before she can, the case's evidence casts doubt on him. With no one she can trust, Maggie is forced to try to uncover the murderers to save herself. When she does, she finds herself staring into the barrel of a gun while a killer says, "Good-bye, Maggie!"
