 While working on the island the work crew finds a large blue rock that they can not move. Unknown to them is that it is a meteorite that fell to earth (Seen at the very opening of the movie). When one of the workers rams the rock (meteor) with a Cat D9 a large blue light is emitted which cause the D9 to stop running. Later when one of the workers goes to use the D9 it starts running on its own and starts killing the workers.
