driving down lover's lane without headlights,
accidentally run down one of the aliens.
Joe Gruen (Frank Gorshin) a drunken opportunist,
comes across the alien's corpse.
He plans to keep the body in his fridge,
but after failing to convince his buddy
Artie Burns (Lyn Osborn) to help him
retrieve the dead alien's body, he returns alone.
The aliens arrive and kill Joe by injecting alcohol
into his veins via their hypodermic fingernails.
Having reported their close encounter to the police,
Johnny and Joan return with the Sheriff,
only to find Joe's body in place of the alien.
The police plan to charge them with manslaughter.
Meanwhile the dead alien's hand detaches itself,
grows an eye, and runs amok.
The military, following a UFO report,
are soon involved.
They surround the alien's spaceship,
but in the end it is the teenagers who defeat
the aliens when they discover
that they cannot stand the glare
from their car headlights."...
