Synopsis
Guilherme (Rafael Morais) and his sister, Sofia (Joana de Verona), live in their grandmother's mansion, occasionally looked in on by their unconventional mom (Beatriz Batarda). Their dad Paul (Daniel Duval), an emotionally distant intellectual, returns to Portugal from Paris. Sofia promised Guilherme that when she was ready, he would have the privilege of taking her virginity. Guilherme starts getting impatient, unable to satisfy himself any longer with masturbating by her side. When he sees his sister apparently having sex with another guy, he feels deeply betrayed. His emotional maelstrom is further exacerbated by the news of their grandmother's death. After their mother decides to sell the ancestral mansion, Guilherme moves in with Paul. Still unhappy, he is once again reduced to self-gratification, this time while watching his father having sex with a prostitute. Before this scene, while father and son play Tic-Tac-Toe, Paul remarks that Guilherme can draw a perfect circle but always loses the game. Reception
Bernardo Sassetti won the Award for Best Music at the 5th Festival de Cinema de Países de Língua Portuguesa. References
