A space probe brings back a micro-organism from Mars which terrorizes passengers at a railhead.
Now yes, this is awful - no budget, poor acting and visual effects from an early 1960's episode of "Dr. Who" - but it is not the worst of these beastie from outer space films I've ever seen. The gist - well an organism arrives on Earth, attaches itself to a couple of unsuspecting people who must not sleep if they are to stay alive. Stuffed full of coffee and amphetamines, they must hole up in an office whilst the powers that be work on some sort of salvation. It's a race against time, and yes also against your eyelids starting to send your brain the "time for bed" message... Actually, Ralph Meeker is Ok in this, but the slightly claustrophobic environment in which much of it is set merely draws attention to the poor writing and pretty unremarkable supporting cast - except maybe the nice but dim 'Hank" (George Flower) who truly is as dense as a rock - and the fact that virtually nothing happens at all until the very, very end... Sorry, this is just boring.
