The Galileo spaceship crashes on the wild and inhospitable surface of a barren planet somewhere in the depths of space. A handful of mismatched survivors (a security officer, the edgy flight commander, a floating circular robot thing and a few faceless randoms) realize that their only possible way of escape is to locate the downed ship's short-hop shuttle pod. But the group discover that the planet's only inhabitants seem to be dinosaurs who are vicious, hungry and on the prowl.
