When the mysterious Joe Smith approaches him with an incredible job offer, Brody thinks it's too good to be true. His life-saving need and his desire to be near the ocean while earning a living are rolled into one perfect job. Rayna Lopez lives a quiet life as she tries to climb her way up the CIA ladder, always in fear the government will learn of her family lineage. When her father asks for help getting her famous and belligerent half-sister out of trouble, Rayna reluctantly agrees to travel with her and they board a yacht where they will be protected. Brody and Rayna realize they've met before, and despite a significant lack of trust between them, they face an attraction neither can deny. As they fight to keep Rayna's sister alive, lies are revealed and secrets are told. They must both learn to trust each other, and-if they live through their voyage-figure out what to do about their whirlwind romance.
