They are here...
A serial killer's execution is faked by a secret government organization, who set him free after injecting him with an alien fetus in order to enable him to find, hunt down and kill the other alien beings who can only survive by inhabiting, and thus destroying, human bodies.
Hud Masters, a convicted rapist and serial killer, must race against time as he defends the human race from these alien beings who themselves must fight against extinction while trying to figure out a way to survive on earth.
With the help of Special Agent Logan, the unlikely anti-hero not only hunts down and fights the alien intruders; he also fights his own inner demons to the bitter end.
