Labyrinth

She vowed she’d never descend into Labyrinth Cave again

Robert Gregor, a young scientist, discovers a moon rock with super conductivity characteristics. But when his mentor threatens to take credit for his findings, he kills him and hides the rock in the intricate caves below Kentucky, before the cops chase him down and lock him up. Two years later NASA is still looking for the rock, and hires Tom Burke, a world renowned cave explorer, to locate it. He descends into the caves with his daughter Cricket, but soon he runs into a group of criminals that are pursuing the same superconducting moon rock. The criminal gang hijack the expedition in the vast underground wilderness, leaving scientist Whitney Burke to go underground and save her husband and child.
