The documentary is an investigation into the life of Mario Wallace Simosen, a man who commanded conglomerates of several companies and was threatened during the Military Dictatorship, when his rights were revoked.

João Goulart (known as Jango) had been democratically elected president of Brazil, but was expelled from office after the coup of April 1, 1964. After that, Jango lived in exile in Argentina, where he died in 1976. The circumstances of his death in the neighboring country were not well explained today. His body was buried immediately after his death, raising the suspicions of premeditated murder. This documentary brings the issue back to the fore and tries to publicly clarify some obscure facts of the history of Brazil.
