Four longtime friends - Francisco, Joana, Simão e Vasco - spend one hot weekend in Francisco's stylish countryside house, right by Alentejo's seaside. Their sunbathing and summer leisure are suddenly interrupted by David's phone call (a former common lover, who left a deep mark in each of them): ten years later, he's back. Suddenly, tranquility is replaced by a boiling tension, motivated by secrets, hidden truths and unanswered questions from all those years ago. All they have to do is wait. But as tensions arise, the questions hovering over each of them is: what will happen once David finally arrives?
