Snack Bar "La Oficina" (The Office), managed by psychological mute Smith and his wife Pruden, is the meeting point for the local con-men (the "los ladrones" of the title). They get together to slightly plan their moves while focusing on social life. Don Anselmo thinks he is the unofficial leader of the band, although he is more the leader they do not have--except when El Escabeche tries to get the rank. Other con-men include Arsenio, who is supposed to deal in antiques; Reme; unfriendly El Carteras or Durán, who is or pretends to be blind; Histrionic chief of police Comisario García is usually too inept to stop the con-men plan... but the con-men are equally inept. This comedy features Spanish humor with all of the usual cast of "españoladas", and those usuals who are not in the main cast... get to the guest appearances.
