In São Paulo, the company of the clothier Carlos is near bankruptcy, with the creditors chasing him and without any order. When he receives a correspondence from a wealthy German entrepreneur, Herr Lachter, proposing a deal of thousands of trousers and jackets, it seems to be the salvation of his company. His imbecile cousin Pepino (Lando Buzzanca) offers to go to Rio de Janeiro first to see the habits of Herr Lachter for a better negotiation. In Hotel Gloria, he collects information from the staff that the German is a lady-killer, having sex with the wives of his clients before signing the contract. Pepino hires Joana Coxalonga (Márcia Dorneles), a street prostitute, to pretend to be Carlos's wife during the dinner negotiation. But when Carlos's wife (Monique Lafond) unexpectedly arrives in the hotel to spend a second honeymoon in Rio de Janeiro with Carlos, confusion begins.
"O Diabo na Cama" is a very silly Brazilian "pornochanchada", with the Italian Lando Buzzanca in the lead role. The story has a good premise and uses many gags, such as the waiter (Ankito) unsuccessfully trying to serve a coffee to Carlos in his room; or the suicidal (Jonas Bloch) that is missing his wife, who left him, unsuccessfully trying to suicide; or the couple in honeymoon unable to be "finally alone". The women are delicious, but most of jokes are actually naive and not funny, picturing the intellectual level of the target audience. My vote is five.
Title (Brazil): "O Diabo na Cama" ("The Devil in the Bed")
