Destiny Rivers, a brilliant poker prodigy who views the world through the lens of game theory and probability, receives a mysterious invitation to an exclusive tournament aboard the Royal Meridian, a super yacht in international waters. The buy-in is ten million dollars, and the prize is a life-changing fortune.

However, Destiny quickly realizes that the host, a ruthless tycoon named Harrison, is playing a game far darker than Texas Hold'em. As the yacht travels into a communications dead zone, Destiny discovers that elimination from the tables carries lethal consequences. Trapped with no way out, she is forced into a tenuous alliance with a fellow player, Rubben Kane, who is hiding dangerous secrets of his own.

To survive the night, Destiny must unravel a conspiracy that links the tournament to the tragic, unsolved death of her father, betting her life on a bluff against a house that never loses.
