Two drunken men stumbling through town encounter a dead, mutilated man inside a parked truck. shocked upon what they see one of the drunks is shortly thereafter attacked and killed by the monsters, thus representing the only males killed by the monsters. Following a montage of additional women being attacked and killed, the police initiate unsuccessful searches for the monsters by tracking the latter's trail of radioactive water. As Hank drives to New York City to obtain a supply of metallic sodium, Elaine performs her own search for the monsters at a local quarry, near where the female travelers were killed. Upon learning this, Dr. Gavin rushes off to assist Elaine, bringing a small amount of sodium with him. As Elaine is testing the quarry water, which registers as highly radioactive, she notices the emergence of a monster. Despite wearing dress shoes she manages to avoid an attack by walking away, but she then falls and becomes incapacitated by a bloody leg injury. Dr. Gavin arrives at her side and, by tossing sodium, kills an approaching monster in a fiery explosion. As additional monsters approach, Dr. Gavin engages one of them in extended Hand-to-hand combat. Hank then arrives with a large supply of sodium, kills the monster that is attacking Dr. Gavin (in the process badly burning Gavin), and with the assistance of police destroys the remaining monsters.
