With each murder more shocking than the last, the survivors grow increasingly paranoid, suspecting each other of being behind the killings. The police struggle to make sense of the complex web of relationships and motives, while the remaining heirs are forced into a deadly game of cat and mouse. Amidst the bloodshed and deceit, the true nature of each character is revealed, demonstrating the lengths to which people will go for wealth and power, all set against the idyllic backdrop of the once peaceful bay.
