Two very different sisters, Mia (still in love with Alejo, the married father of her daughter) and Britt (the ice maiden, who has ironically written a romantic bestseller), join a luxury honeymoon cruise in the Caribbean where Britt is the guest lecturer. Also on board are recently widowed Leo, still reeling from the discovery of his wife's betrayal just before her death, and Steve, a ship's officer who's soon looking for more than a holiday romance with Mia. Can Steve replace Alejo and is there any chance that Britt and Leo can see that they really should get together?
