Tudo Dentro(1984)

Rui decides to value his motel and for that he creates a formula in which he believes to offer surprises to his customers, surprises that are presented at the motel's reception. He invites a receptionist to help him, who becomes very fond of him. René, with a telescope, accompanied by the receptionist, manages an inflatable dinghy on the lake that borders the motel and looks through it and through mirrors properly placed in the chalet's stained-glass windows at the various situations that unfold from the surprises offered to customers.
