When four teens discover their little town is being invaded by creatures from another world, they reluctantly set out to battle the extraterrestrials. However, the enemy has special powers one of which is melting metal.

But can their primitive arsenal be effective against high-tech laser pistols and rifles? However, the teens have learned a secret about the aliens that just might tip the odds in their favor.
