A group of female soldiers are to be transported, via a new invention, to Germany. Only they end up in the center of the Earth. The creator of the device (Greg Evigan) is able to trace their marker and wants to rescue them. Why he thinks they are still alive I don't know. Since the transporter isn't working he goes to a fellow scientist (Dedee Pfeiffer) who has this burrowing machine (like in AT THE EARTH'S CORE)--and they burrow down into the earth to rescue them. The movie goes back and forth to them and the soldiers. They encounter a Tyrannosaur, we see some flying reptiles, they cross a bridge over lava, encounter carnivorous plants and also giant spiders. Everything you expect. The lame producers (The Asylum) could have easily titled this movie THE LOST WORLD since it follows the 60's movie version of that novel more closely.
