Caved In: Prehistoric Terror is a 2006 "Sci-Fi Original" motion picture, created by the Sci-Fi channel. It follows a party of tourists who become trapped underground by a cave-in, and who are then killed one by one by giant prehistoric rhinoceros beetles. The movie is infamous for its not-so-subtle "kill lines". These kill lines are lines said by actors right before they are killed, essentially telling the viewer how they will be killed; e.g. right before getting one's head sliced open, one would say: "Argh, I have a splitting headache!" The film is one of many Sci-Fi originals that focuses on being trapped in a confined area while being hunted by mutated species.

Three humanoids who arrived on Earth face the task of returning a scientist who disappeared 20 years ago. By chance, the adventures of these aliens begin with a meeting with the local criminals, which entails a stream of unexpected problems. The appearance of their earthly ally Marat draws them into a new maelstrom of events that they must overcome together. A small village is expecting a big commotion...
