Due to a scientific experiment gone awry, a research team ends up in a strange land below the earth's crust. There they must fend off a series of strange creatures, including vicious dinosaurs and spiders. Meanwhile, above ground, Emily Radford (Dedee Pfeiffer) helps military official Joseph Harnet (Greg Evigan) with his plan to save the stranded research team. Their strategy is to use a high-powered drill to bore their way to the researchers, one of whom is Emily's sister. Wikipedia
