When a Spanish Jesuit goes into the South American wilderness to build a mission in the hope of converting the Indians of the region, a slave hunter is converted and joins his mission. When Spain sells the colony to Portugal, they are forced to defend all they have built against the Portuguese aggressors.

The time is a future where humans have moved their residence to the moon.... In the lunar colony, a game has become very popular. The name of the game is "Run for the Money." It is an entertainment survival game in which fugitives are released into a limited area, and if they can escape from the pursuing android "hunters" until the time limit counts down to zero, they can win a large prize. Some dream of getting rich, while others challenge themselves to test their strength in "Run for the Money."
