The movie begins with a shot of a meteorite heading towards Earth and crash landing on a remote island about 200 miles off the African coast. The fact that it glows blue and makes a strange humming sound lets us know from the start that it is not an average space rock. On this island is a small six man crew, headed by hard nosed, ex-alcoholic Lloyd Kelly (Clint Walker), who are paving the way for an oil drilling team to set up camp and begin operations. When a massive D9 bulldozer plows into the fallen meteorite, the blue light transfers from the rock to the dozer and a nearby crewman (Robert Ulrich) suffers what appears to be severe burns. Before he dies he warns Kelly of the blue light and no sooner are the men warned, then the D9 starts to act like it has a mind of it’s own and before you can say “KIlldozer” it’s stalking and killing the team members like a big yellow Michael Myers on his favorite holiday.
