René Cardona Jr. - La casa que arde de noche (1985)

Quote:
A prostitute enters a brothel and establishes a rivalry disguised as affection with the old owner. She manages to take over the business and the old lady’s lover. After disputes with her now lover, she leaves the brothel, only to find out the next day that the old lady has died. Then, due to a passionate outburst, the new owner sets fire to the brothel and dies along with her lover.
