One of 4 things happen.
First, he buys a trip to Mars and gets the spy special. It plays out exactly like that.
Second, he buys a trip to Mars and is actually on the table about to get lobotomized because it went wrong.
Third, he is part of the resistance working against the bad guys.
Fourth, he is part of the bad guys falling into the resistance, and then destroying them from within.
Every one of these plots are presented without ambiguity and can be taken for granted and truth as is.
This "dumb" sci-fi action film is probably the smartest movie in the genre.
