SPACEMEN takes place in an alternate (but pretty similar) 1967 AD, where public space technology is a little more advanced. Doctor Curtis Temple, his assistant and lover Lee Mason and his offsider Alan Mollay are called in to investigate a strange coordinated landing of "meteors" in Cornwall, UK.
It soon proves to be nothing less than the vanguard of an alien invasion!
The aliens unleash horrors on the local population whilst Dr. Temple does his best to fight them as a one-man scientific army, until he finally enlists the aid of some allies and tries to turn the tide of battle against the alien invaders...
