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 Bruno¹s sister and Marta¹s best friend and would love to see her brother happy; Carlos, Jorge¹s 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 emprision him and, convinced that his love and his lover¹s desire to marry will take away his freedom, decides to show her the way into Carlos arms.
