 Unable to raise enough money through donations, Sister Bertrille thinks they should go into business. With the donation of the raw materials, Sister Bertrille thinks they should produce what she calls the Nectar of San Tanco: sea grape juice. Out of faith, Carlos and one of his business associates, Luis Fiero, agree to exclusive distribution rights of the product without even knowing what it is. When Carlos finds out it s sea grape juice, he pulls out. The business is in trouble when the creditors come for payment and the sisters haven t sold a bottle s worth. Luis Fiero changes his mind and decides to distribute after sampling the product and seeing Sister Bertrille fly, thinking that the strength of the nectar was the reason for his vision. But because the bottles of juice have been sitting around, they have also been fermenting and turning into wine. So when Carlos delivers the bottles to Luis and needs to go through customs, he is arrested for trying to smuggle sea grape wine. The customs inspector raids the convent. However in the meantime, the juice and the wine has made yet another transformation, this time into vinegar. Fiero buys all the bottles of vinegar anyway, the sisters stop production and after paying the creditors, end up twenty-five cents in the red, the twenty-five cents paid by Carlos. He knew this venture would cost him something.
