Tour operator Alex Trotter is back to escort vacationers on more adventures. Now she has been hired by a former schoolmate to arrange for her wedding/honeymoon cruise on the Bermuda Queen. Alex predicts a "sea of trouble" ahead when she learns that the groom is the notorious global art dealer Victor Garza, and that the guest list includes warring family members, a vengeful ex-partner, and a few clients he has cheated. Alex invites her new love interest Detective Arlie Tate to come along. Together they encounter eccentric people and questionable activities on board the ship. When one of the party is found murdered, they must unearth secrets and lies to expose the killer on board before someone else is killed.
