Benjamim tells the story of a dangerous passion in two time frames, separated by a lapse of 30 years. Upon meeting the young Ariela Masé, who has an astonishing resemblance to the great love of his past, the experienced and forgotten publicity model Benjamim Zambraia relives the joys and horrors of love. The "reincarnation" of his beloved Castana Beatriz has something else to offer him: a coming to terms with his own conscience.
