"Frontalwatte" is like running against a hard wall and falling down softly. Franz, Adrian and Anastasia stumble through a pointless world. They kill time by viewing apartments, jaw operations, incest and poetry slams. Their search for identity becomes a search for the best fitting role.
When lovelorn Michael arrives in Berlin to return a set of keys to his ex-girlfriend, Gabi, as an excuse to see her again, he finds her apartment empty save for a couple of plumbers making repairs to the central heating. Just as Michael learns from the plumber’s apprentice, Harper, that Gabi has popped out for a while but will return soon, the apprentice is attacked by his boss who has unexpectedly and inexplicably transformed into a raging madman. Together, Michael and Harper manage to bundle the crazed plumber out of the apartment and barricade themselves safely inside. Within minutes, they find themselves trapped in apartment block under siege from a horde of similarly insane people, apparently hungry for human flesh.
