A small colony terraforming a barren planet are surrounded by asteroids. The story focuses on a man whose job involves clearing a path while supplies are shipped in. At the same time, he deals with his collapsing marriage. Then, his life goes wrong. His wife reveals she's having an affair with one of the guys on the shipment run. In a moment of weakness, he lets the next ship get hit. When he returns to the surface he's fired, and finds that his wife's lover had stayed behind. Furious, she leaves him. News gets around, and he's put in jail. However, his replacement sucks. With the colony on the verge of disaster, he is released on the condition he clears the path as a punishment. When the next shipment is safely on the ground, they call him back down, offering him a full pardon.
However, he's finished with the colony and, in an act of defiance, he flies off through the open path, resolving to leave that barren piece of rock in hopes of greener pastures.
In the original ending, he chooses suicide, and flies headlong into the asteroid field.
The main character is to be played by Bruce Willis.
