It starts off with a quivering pile of lopped off hands; it then continues with a rust-coated 50's-era robot zombie machine-gunning down squealing Japanese teenagers in a subterranean parking garage. But the trailer doesn't truly get special until you see the title... Mikadroid: Robokill Beneath Discoclub!
The plot is simply unnecessary elaboration upon that title.
The robot zombie also has a lightsaber, by the way.
