Outland

On Jupiter's moon he's the only law.

Io, Jupiters innermost moon, hosts mining colony Con-am 27, a high-tech hellhole. There Marchal William T. O'Niel probes some mysterious deaths among the miners. In pursuit of the truth, he's alone.
In Outland, writer/director Peter Hyams depicts a chilling extension of today's corporation-driven world.
