A concierge of an apartment in Barcelona named Cesar is on the roof of a building explaining his nature of not being able to find any happiness no matter what he does or what good things happen to him. As he wakes up in Clara's apartment and begins his routine working in the main lobby, He gives hush money to Ursula, the daughter of another tenant. Cesar visits his sick mother in the hospital, who is practically unable to speak to her son but listens to him talk about Clara. Veronica, another tenant, asks Cesar to take care of her dogs giving detailed directions on how to feed them. Cesar ignores her instructions and feeds her dog Rocio a slice of pie. Clara, entering her apartment, opens up letters she has received then tears them up and throws them away all. While this is happening, Cesar hides under her bed waiting for her to fall asleep in order to use chloroform to keep her asleep so he can maliciously mess with her care product. The morning after, he sneaks out of Clara's apartment with Ursula waiting outside. She demands that Cesar provide her with an adult movie if he wants her to keep her mouth shut. Cesar, working in the lobby, finds Veronica heading out of the apartment. He questions Veronica where Rocio is and she explains that Rocio has horrible diarrhea from something he may have eaten.
