The real story of Carlos Lamarca, a captain who, during the military dictatorship in Brazil, deserted Brazilian Army and got involved in left-wing guerilla groups, becoming one of their most prominent leaders.
Mid-1970s. When the military regime's "economic miracle" and the victory of the Brazilian football team on the World Cup serve as a distraction for the persecution of opposition leaders by the political police of the dictatorship. Under this context, Jofre Godoi da Fonseca, an alienated middle-class man, is mistaken for Sarmento, a political activist he met at an airport prior to his assassination. He is then arrested for being "subversive".
Anabela, una bella y talentosa bailarina, aparece muerta flotando en un lago. La policía rápidamente asume el caso como un asesinato, pero cuando los residentes de la pensión donde también vivía Anabela comienzan a ser entrevistados, la policía se da cuenta de que todos tenían al menos una razón para matar a la chica, lo que complica la investigación del caso.
