Rammbock

When heartbroken Michael travels to Berlin to return Gabi’s keys, hoping for a chance to see his ex-girlfriend again, he finds her apartment empty except for a couple of plumbers working on the heating. Michael quickly learns from the plumber’s apprentice, Harper, that Gabi is out but expected back soon; however, chaos erupts when the apprentice is suddenly attacked by his boss, who has inexplicably turned into a crazed lunatic. Together, Michael and Harper manage to force the deranged plumber out of the apartment and secure themselves safely inside. Moments later, they discover they are trapped in an apartment block overrun by a horde of similarly frenzied individuals, all seemingly driven by an insatiable hunger for human flesh.
