Story is set in the late 1970s, somewhere in the Mediterranean, where Marcos Timoleon (Dafoe), an Onassis-like tycoon throws a lavish, extravagant birthday party for Sofia, his daughter and sole heiress on his exclusive private island. Marcos, used to ruthlessly controlling everything and everyone around him whatever the cost, is also secretly plotting a big decision on his daughter’s behalf. As guests start pouring in and the night moves on, the party grows rowdier and more decadent, while the inevitable clash between Marcos and Sofia thunders towards its shocking conclusion.
