1989: The tunes are loud and the clothes are louder when a group of friends arrives in Mallorca for a post-graduation holiday of decadence and debauchery at a luxury villa.
A beach party marks the pinnacle of their fun, until it isn't fun any longer. Because amidst the wild partying - sand flying from dancing feet and revellers leaping from yachts - an accident happens. Suddenly, the night of a lifetime becomes a living nightmare.
Now: The truth about that summer has been collectively buried. But someone knows what happened that night.
And they want the friends to pay for what they did.
