The city bustles by day, but by night the streets are abandoned. The gangs are fighting for supremacy and the police have already lost.
Sebastian, a reclusive genius, becomes unwittingly embroiled in the criminal conflict while taking odd jobs to make rent and so impress the landlady he's smitten with. As his work begins to directly impede the income of the city's most powerful gang, it's only a matter of time before the faceless mastermind, Diamond, discovers the identity of the culprit and launches a manhunt to smooth over the financial strain in the only way the criminal underground allows.
Meanwhile, Troops don supercomputer battle armor to wage war against an underworld stronghold headed by the survivor of a genetic experiment with superhuman strength and no shortage of skeletons in his closet; the world's deadliest assassin - rumored to possess supernatural powers - comes into town, tracked by a mysterious stranger not so unlike a demon; and a multinational technology firm with insidious intentions, vast political connections, and a bold young leader begins making ambitious maneuvers, some of which involve one very particular landlady.
But there is always a cost, and the Impossible Man knows it best.
