Sinisterly handsome Victor, a real estate agent in Madrid's gentrifying, candy-colored “gayborhood,” hides a wicked little secret--he murders old ladies then flips their renovated flats to upwardly-mobile gays. When bearish working class lovers Rey and Leo inherit the latest victim’s apartment, they move Rey’s acerbic mother in. Now it’s up to an eccentric detective, her sexually confused son and the unwitting couple to uncover the murderous scheme before he strikes again.
