In Lapa, Rio de Janeiro, the idle aspirant writer Zeca (Caio Blat) has been living with the Arts Professor Júlia (Maria Ribeiro) for five years. His novel has been in stall on page 50 for a long time and Zeca claims lack of inspiration to conclude the plot. He has a comfortable life with the inheritance left by his mother and administrated by his father Humberto (Daniel Dantas) that criticizes him, since Zeca is almost thirty years old and has not come of age. When Zeca sees Júlia alone with her best friend Carol (Luz Cipriota) in his flat, he believes that they have a love affair and he becomes obsessed for Carol, following her on the streets. When Júlia travels to São Paulo for a Congress, Zeca has an affair with Carol. Then, while Júlia works and studies for her doctorate, Zeca has sex with Carol during the days and with Júlia in the nights. Zeca plots a scheme to stay with either Carol or Júlia but his plan does not work well."Histórias de Amor Duram Apenas 90 Minutos" is a delightfully witty and sexy romantic comedy, steamy and erotic but never vulgar. The cinematography uses the style of film-noir and the screenplay is pleasant and charming. The Argentinean Luz Cipriota is really a pretty and sexy woman and Maria Ribeiro is also very beautiful and hot. Caio Blat is an excellent actor but either Luz Cipriota or Maria Ribeiro is absolutely out of his league. My vote is eight.Title (Brazil): "Histórias de Amor Duram Apenas 90 Minutos" ("Love Stories Last Only 90 Minutes")
