Nurse (Elisabetta Velinska) is a minor antagonist in the 1961 Italian comedy film "I Tre Nemici".
The Nurse is an enemy spy under the employment of Dr. Otto Kreutz (Martin Benson).
A scientist develops the formula of a new, powerful explosive, but his maid, who is actually a spy, kills him and steals the formula. The spy then pretends to be a tattoo artist, and transcribes the formula, in the form of a tattoo, on the butt of Leo Bottini, an employee who works in a tourist agency.
The enemy spies, captained by Dr. Otto Kreutz, try in every way to steal from him the secret that he wears without knowing it.
Leo first visits the doctor office of Kreutz who is being assisted by the blonde nurse. After showing him into the office, the nurse introduces him to the doctor. When Dr. Kreutz asks Leo to strip down, he is reluctant to do so with the nurse in the room.
When Leo is afraid of the injection needle, the nurse brings the doctor a tranquilizer in the form of a pill. Leo is once again afraid to take it, so the doctor takes one to show him it is harmless. Once Leo takes one, they both pass out.
The nurse comes in and noticing that both the doctor and Leo have passed out, pulls out a camera and takes a picture of the formula on his backside. She then takes out a pistol and is about to shoot Leo, when she is distracted by two visitors in the form of Rocco (Ciccio Ingrassia) and Fanbuzzo (Franco Franchi) who are also there to steal the formula. While Fanbuzzo distracts the nurse by having her look at his faked sickness, Rocco steals the camera with the picture that she just took.
When Rocco and Fanbuzzo leave, the nurse notices that they took her camera. She chases them outside and shoots unsuccessfully at them. When they drop the camera, she retrieves it and finds that the film has been exposed to sunlight and is useless. The nurse is then arrested by a policeman and put into the police car for possessing a gun.
