It's a Friday night in Rome. The weather is mild and the people of the night are ready to go out and have fun. In a room in one of the liveliest quarters of the city, two strangers meet. Both of them are about thirty, alone and looking for someone to spend the evening and maybe, who knows, even the night. She asks for a passage and he agrees to accompany her by car to the other head of the city. Here they are together that they go wide through the night.
