Rebeca and her family move into an abandoned house with a sinister past. Her father wants to renovate the house and turn it into a rotisserie. With the help of her neighbor Lucas, Rebeca discovers that the former residents were attacked by a strange creature: The Killer Lasagna. The monster gains strength and grows as it feeds on the remains of food thrown down the pipes and, at the opening of the cantina, the Lasagna will attack again.
