Based on the novel by Karel Capek, the prominent Czech writer of the early 20th century who coined the word robot for his play R.U.R., the story revolves around a discovery of Krakatit - a powerful explosive - by Prokop, an experimental scientist who, following an accidental explosion in his lab, slips in and out of delirium. When he realises that, in a delirious period, he has given the formula for making Krakatit to one of his colleagues, he tries to find the man, who does not realize how dangerous a thing Krakatit is. In the process, he nearly gives his discovery away again to foreign interests, a group of anarchists, and even greater forces of darkness...
In the distant future, a large portion of humanity lives on Mars, in cities that resemble those once found on Earth. The cities are protected from the inhospitable Martian atmosphere by dome-like force-fields. When a massive sandstorm breaks through the dome and destroys Mars New York, those in Mars Los Angeles must figure out how to stop the storm before it wipes them out next.
