Lorca and the Outlaws (1984)

Things are not going well on the mining planet Ordessa: the conditions are awful, the workers are disgruntled and the management is cracking down by using killer security robots. Only the underground resistance movement, led by Lorca, has a chance of turning around the brutal regime, but the management has hired Danny the bounty hunter to track down him and his followers. Will any of them stand a chance against the brutal hunter and his robot assistants?
