The Rayburn family are the toast of the Florida Keys, a well-to-do bunch that occupy a place at the heart of the idyllic American Caribbean community - home of white sand, blue seas and the 2 o'clock cocktail.

Spirits are high with patriarch Robert Rayburn set to have a pier renamed in his honour, and his extended family are planning a party to celebrate.

Danny, the black sheep of the family, is headed back to the islands to join in the festivities, and the Rayburns are nervous about his imminent arrival. But what seems like a simple matter of family politics proves to be far more fraught that anyone had imagined.

And his return is only the beginning. What happens next, none of the Rayburns saw coming.
