Mari, a 14-year-old teenager, is searching for her missing brother. Her investigation leads her to cross paths with José, a mysterious man who works exclusively at night so as not to reveal the secret he hides. Mixing different formats such as film, digital, and handycam, Piel de cerdo is an aesthetic, sordid, and raw experience that seeks to pay homage to the giallo cinema of the 1960s and 1970s.

Fed up with being treated like criminals by the elite they serve, two valet drivers at a high-end restaurant embrace the prejudice and vanish into the night in a stolen car.
