It's High Noon in outer space as mining colony marshal Sean Connery confronts the pushers peddling lethal drugs to Jupiter moon workers so they'll produce more ore. This bleak dramatisation of final frontier contamination comes complete with Alien-inspired decor and smooth direction by Peter Hyams. But eschewing the cleverness of his Capricorn One for a doggedly one-dimensional approach to both plot and character, Hyams sinks this far-flung fantasy with cheap scare tactics, illogical science and B-movie western-style gun battles that scupper credibility. And why does Connery never call for back up?

On the sunless moon Io, Marshall William T. O’Niel goes toe-to-toe with the corrupt manager of a mining colony and his gang of roughnecks while investigating a rash of worker suicides.
