When night falls, Prudencio disguises himself as a vampire and an old Green tail to seduce Florinda, Malena and Eva, his three neighbors. Meanwhile, the dangerous criminal nicknamed the little boy escapes from jail to kill Prudencio who stole Florinda's heart. Eva's suitor is a policeman who follows Chiquilín's tracks to capture him. Malena tells Prudencio that she had a daughter with him and forces her to recognize him. Prudencio's friend, Bad luck, seduces Florinda and Malena kidnaps Prudencio so that he does not abandon him. Finally the commander catches the Chiqilinín and Malena frees Prudencio to form a couple with Prudencio's uncle who comes from a town and with whom he bears a striking resemblance. Thus, the uncle recognizes Malena and her daughter as his new family.
