The Counterfeit Constable

Frenchman Dhery goes to London with a group of his friends to see a soccer match. While waiting to see a dentist there, he playfully dons the uniform of a British policeman and scares away some thugs about to rob Diana Dors. He's afraid to open his mouth to explain his situation because his two front teeth were knocked out earlier, so a long chase follows until he takes off the uniform. Diana Dors has never looked as sumptuous.
