Before recorded history, an alchemist combined with an unknown element from another universe and was transformed into an indestructible monster that could change from a solid, liquid, and gas, and consume all living matter into oblivion. The alchemist's apprentice endeavored across the span of millennia to destroy the Master, until present day, when The Gate attacks Jimmy and Lauren's home. Their lives have been darkened by The Gate, but they must accept the revelation of the past and seek vengeance to save the lives of their friends, their world, and ultimately the universe. To destroy the monster, one will have to become the monster.
