Marta and Jorge have been a couple for seven years. All their friends think they are living a perfect romance. Too perfect, perhaps, for the despair of all: Bruno, who is much younger than Marta but madly in love with her; Lígia, who is Bruno’s sister and Marta’s best friend and would love to see her brother happy; Carlos, Jorge’s friend, who maintains a superficial romance with Lígia while secretly in love with Marta; and for Jorge himself, who is afraid this idyllic romance will imprison him and, convinced that his love and his lover’s desire to marry will take away his freedom, decides to show her the way into Carlos arms.
