A mysterious invitation, a dinner party on a tropical island, and ten strangers will be thrown together into a plot of murder, deceit, and revenge. In a race against time, it becomes apparent the killer is among the guests. They must work together to solve the case, but who can you trust when the enemy hides among your allies?
