Suave playboy Rafael (Guillermo Toledo) works in the women’s clothing section of a department store (think Marks & Spencers), a fertile area for his conquests of the female variety. When Rafael gets into an argument with a co-worker, who coincidently is competing for a promotion that Rafael covets, actions turn deadly. One dead body later and Rafael must dispose of the bloody carcass.
Meanwhile, a dowdy secret admirer named Lourdes (Mónica Cervera, 20 Centimetres) promptly jumps in to help; after all, she saw the murder happen and its the least she could do. But her assistance has a steep price. Rafael must reliquish his swinging lifestyle and get married to her! So what is the crime? Marriage? Murder? Lourdes's appearance? Rafael's situation is far from perfect, which could easily make this the "ferpect" crime.
