To access a cache of geothermal energy buried deep inside the Earth's crust, a team of scientists (led by Dana Andrews) decides to detonate an atomic device ... despite one doctor's (Kieron Moore) dire warning that doing so could prove deadly. Now, as a result of their actions, Earth's surface has begun to crack, and everyone on the planet could perish. Andrew Marton directs this scientifically improbable sci-fi classic.
