Young Arabella Arabella (Tini Cancino) and Francesco Francesco (Francesco Casale) are involved in a car accident on their wedding day. Arabella was fine, while Francesco hurt his leg. Now, he is in a wheelchair. After the accident, Francesco, as a writer, not only lost his creative inspiration, but also could no longer have normal sex with his wife. So Arabella lived a double life in pain, gathered affectionately around her husband during the day to help him restore his health and creation, and went to the city at night to seek the release of sexual desire. In fact, it was Francisco who wanted to stimulate his sexual fantasies through these inappropriate stories to ask her to bring her night experience home. It is because of its inspiration that Francesco has begun to write a novel entitled "Black Angel", which involves Arabella's pornographic narratives. As everyone knows, the crimes hidden around this boring couple follow one after another.
