A lonely beach on the southernmost coast of Brazil is the scene for two friends on the brink of adulthood to explore their understanding of themselves and one another. Martin (Mateus Almada) has been sent by his father to retrieve what appears to be an inheritance-related document from the family of his recently deceased and estranged grandfather. Tomaz (Mauricio Jose Barcellos) accompanies him seemingly hoping to regain some of their former closeness. The two boys shelter themselves in a glass house in front of a cold and stormy sea.
