Devil Girl from Mars (1954)

In a Scottish inn, the owners, employees and guests are united in the bar. Out of the blue, a flying saucer lands nearby and a woman dressed in black leather like a dominatrix with a cape arrives in the bar armed with a ray-gun. She explains that she is Nyah from Mars and she was heading to London, however her spacecraft collided with an airplane and was damaged; therefore she had to land to repair the saucer. She also explains that she is looking for men to breed with females of her race since the male population is dying after warfare between men and women and they need offspring. Nyah has the robot Chani to help her to capture men, but she wants that one of the men volunteers to go with her to Mars. Who might be the volunteer?
