Blackmail. It’s such a dirty word. All Short Man wants is a friend. Someone to go for a drink with, someone who’s always there to listen. All Tall Man wants is his identity as an illegal immigrant kept secret, and so he agrees to become Short Man’s friend. But Tall Man is about to find out just what a high price he has paid to buy his blackmailer’s silence. Short Man and Short Woman live in the apartment above Tall Man and Tall Woman. The men initially do not know each other, until Short Man bumps into his neighbour in a local café. Before this, they had never exchanged more than a few words, passing only on the stairs as Tall Man left for his night job and Short Man returned from his day job.
