After a good-hearted outlaw turns himself in for
a fatal accident, the guilt-ridden Sam Phoenix is ready to be hanged
when an unexpected pardon arrives in the form of an alien-insect invasion.
As the bloody killing spree begins, Sam and a small number of
survivors are forced to take refuge in a nearby church. Realizing
they are going to need a lot more than a prayer and a pistol to survive this nightmare,
the small
community enters a showdown where only one species will make it out alive.
