With the cyclotram, an atomic-powered rock-boring vehicle, Dr. Jerimiah Morley leads an expedition into a subterranean world.
Subterranean shadows and low-budget atomic wonder define this claustrophobic journey into the earth's core. A drilling machine carries a desperate crew toward a strange, hollow civilization hidden beneath the crust.
