On the great plains of the old American west, enormous steam-powered
robots march across the countryside. Their mission: to defend the
populace against invading Martians and armies of killer albino apes! The
Steam Man, a giant metal man operated by a team of monster hunters,
seems to have the defense of the West well in hand, until a crazed and
powerful vampire comes to town with the intention of bringing forth the
apocalypse!
