Devil Girl From Mars

One winter evening in a lonely Scottish inn, guests become prisoners when Nyah, a pitiless Martian with a robot minion, lands on earth and traps them within an invisible wall. With Martian males extinct after a battle of the sexes, Nyah aims to capture breeding stock on Earth. As escape attempts falter, the helpless humans must decide which one of them will die to save the others and possibly the world. (StudioCanal UK)
