Mainspring – a quaint town removed from time and era. Powered by steam and clockwork, Mainspring has enjoyed decades of peace and prosperity … until, from a far-away land known as The Keep of Keys, Hieronymus Ebauche unleashes Hell. Born of a long-forgotten vendetta, Ebauche transports his clockwork demons through a trans-dimensional portal to exact his revenge. Mainspring's only hope – Nathan Gage and Olivia Nightingale; the proprietors of the Klockwerk Kabaret, where desire is brought to life with flesh and clockwork. When the doors to the Kabaret close, Gage and Nightingale slip into the shadows as vigilante crime fighters. The fight leads them to The Keep of Keys where they discover a much darker truth. As the clock winds down, so too does the hope of Mainspring.
