Two private investigators pretend to be newlyweds in love on a Caribbean honeymoon cruise to catch a killer, but what happens when make-believe feelings turn real?

Former Navy SEAL, Callum McKenzie, struggles to open himself up to love. So, when he books a ticket on a honeymoon cruise for a case, he has to find someone to play the role of doting wife. He hires someone, based on a recommendation from a friend, but when he meets the petite single mother, Callum has misgivings. He’s attracted to her in a way he’s never felt before, but he’s her boss. Can he keep things professional between them and fight his forbidden feelings long enough to solve the case?

A former beat cop, Jessie Arwens, moved back home to Atlanta after losing her husband. All she wants now is to see her son settled in his new school and to start over as a private investigator. An old friend recommends her for a job with a successful local PI and she jumps at the chance to establish herself. When she meets him, she quickly finds herself caught up in their act. But she’s been burned by love before and doesn’t want to risk her son’s happiness by leaping into a new relationship, especially with the man who’s currently paying her wages.

Cruising through the tropical Caribbean, the two of them uncover a nefarious plot and web of lies on their pretend honeymoon. But they soon discover that when it comes to matters of the heart there’s a fine line between make-believe and reality.
