An Argentine family travels to Brazil. Inside the car are Lucrecia and Pedro (psychologists) and their two adolescent children.
Lucrecia and Pedro have been “technically separated” for a few months (that is how they define their situation), after decades of marriage.
Pedro and Lucrecia feel the need to take vacations together. Marco, the Brazilian that rents the summer house to the family, Larissa, his ex-girlfriend and Cesar, Marco’s son, become friends with the Argentine family. Marco encourages enjoyment of the present and awareness of how short life really is. Attracted by Marco, Lucrecia has an affair with him. Pedro, bewildered, discovers Larissa’s charms and spends time with her. He wants to take advantage of the time he has with the Brazilian before she travels to San Pablo and the summer ends.
On the beaches, between waves, karaoke bars and aquatic rides, crossed romances are born alongside an attraction that also splashes onto their children and others. The children make the most of it, living their experiences, and everything gets a bit more mixed up.
