The Vivero Letter (AKA Forgotten City) is the story of a man who finds the murdered body of his brother. The murder is linked to a lost city in the jungle. Joining a search expedition, the man realizes that most of the members plot to betray each other, leading to a bloody showdown in the jungle wilderness. There is also time for a couple of nude actresses, fortunately for us. First Daniela Alviani shows us her boobs while having sex with a man in the jungle, then Chiara Caselli unbuttons her shirt and shows her breasts to a guy in a mysterious dungeon.
