This releases an ancient being composed of pure energy, left over from a war involving sentient machines in a long-lost civilization, which "possesses" a bulldozer being used by the construction crew. The being's purpose was to take over the "enemy's" machines and attack the enemy. When released from the ancient stone temple that contained it, it believes that the bulldozer (called "Daisy Etta" by the workers in the island, a mispronunciation of De-Siete - D7, in Spanish) is important to its intentions, possesses it and it begins killing the workers. Ultimately, two of the three surviving workers—one goes insane—manage to destroy the bulldozer and (presumably) the creature.
