Reporter Lawrence (Robert Clarke) arrives in the remote Highlands of Scotland to visit a professor (Raymond Bond) who is observing a strange new planet that has appeared. The planet is getting closer and will be at it's closest over their remote Scottish village, Lawrence is interested though probably a bit more in the professor's daughter Enid (Margaret Field).
Enid observes a strange vessel nearby, upon investigation they encounter a strange man in a suit, a man from another world. He needs their help but the unscrupulous assistant of the professor, Dr Mears (William Schallert) beats the alien up to try and get his secrets so he can rule the world. This obviously annoys the alien who begins to enslave the villagers so he can facilitate an alien invasion...
So, the plot is fairly unoriginal (and there was no shortage of films like this in the 1950s!) The effects are rather cheap and laughable but the remote Scottish setting and the ambiguity of the alien intentions adds some interest to the film.
