The home of acclaimed Chilean filmmaker Ignacio Agüero is often interrupted by an unending stream of people knocking at his door: poor people asking for food, friends, neighbors, etc. Agüero turns the tables on his uninvited guests, and asks them if he may knock on their doors too. His spontaneous excursions into their neighborhoods and homes broaden the film's scope, bringing different aspects of contemporary Chilean society into the picture.
