chunk: The film opens in what will become North Texas, 35,000Â BC. Entering a cave, two cavemen hunters stumble upon a large extraterrestrial life form. One is killed by the creature while the other one fights and wins, stabbing the creature to death, but he is also infected by a black oil-like substance which crawls into his skin. In 1998, in the same area, when a group of boys are digging a deep hole, a young boy named Stevie falls down the hole and finds a human skull. As he holds it, black oil seeps into his body until it reaches his head, causing his eyes to turn black. Later, four firefighters descend into the hole to rescue him, but do not come out. A team of biohazard-suited men arrives on the scene.
