Barrios bajos (The Slums) is a 1937 Spanish black-and-white film directed by Pedro Puche. It is a melodrama that has been noted to possess some formal elements that foreshadowed neorealist cinema. It was produced by a team of the anarchist Union of the Entertainment Industry Films (SIE Films) while film production in Barcelona was collectivized by the CNT.

Plot

The plot concerns an erotic triangle formed by Ricardo, a lawyer who has assassinated the lover of his wife and is searching a place to hide from the police; Rosa, a young attractive woman who had to leave the wealthy house where she worked as a maid because of a case of sexual harassment by the owner of the house; and El Valencia, a port worker who hides Ricardo as a repayment for an old case in which Ricardo defended him on the court and who defends Rosa from an evil procurer, Floreal. El Valencia is the protagonist and the hero of the film, opposed to the evil Floreal.
