The plumber (Ivar Kants) shows up at the door of well-to-do Australian couple Robert Coleby and Judy Cowper. Though the plumber apparently hasn't been summoned, he is given unquestioned free reign in the household. He ends up staying several days, his work and personality growing weirder with each passing day. Housewife Cowper is driven to neurotic distraction by the plumber's presence and by his iconoclastic attitudes towards everything she holds dear. Then, the plumber walks out of the flat, never to return...leaving behind a residue of paranoia and shattered values. Filmed for Australian television, The Plumber may well be the most maddening 76 minutes ever committed to celluloid. Naturally, it only served to further the reputation of its gifted writer/director Peter Weir.
