The late 1970s. On a private island in the Mediterranean, Markos, a powerful billionaire, hosts a lavish party for the birthday of his daughter Sophia—the sole heir to his enormous fortune. The party becomes an opportunity for friends and partners to approach the host with questions and to have their problems solved at his expense. But Markos himself is preparing an important decision that will determine his daughter's future. However Sophia has her own secret and her own purpose. And as the night grows louder and more unrestrained, the family conflict comes to the surface.
