João Vuvu, a widower with no family, lives alone in his own, large, sunny house that shows signs of wealth in an old neighbourhood of Lisbon.
João Vuvu is not very sociable, if at all, and every day takes a trip on bus number 100, untiringly repeating the same route.
When his son gets out of prison, the deception that his desire for regeneration provokes in his father will unleash a series of sombre events in which the protagonist’s criminal inclinations come to the fore and condemn him to a destiny that is definitively that of an outlaw and as a marginal figure.
With due differences, two striking cinematographic references: The fatal glass of beer by W.C. Fields and Monsieur Verdoux by Charles Chaplin.
