to produce energy for a desperate, war torn Earth. Crater Trueblood, an
orphan, loves his life in Moontown, a frontier mining settlement. Just turned sixteen, Crater is already a seasoned Helium 3 miner, hoping someday to be a foreman on the scrapes. But "the Colonel," the man who owns the mine, has a different plan for Crater which includes Maria, the Colonel's daring young granddaughter.
