Left on the doorstep of a monastery as an infant, Marcelino was raised by the monks. He was well-cared for but lonely and missed having a mother. One day he found a special friend in the forbidden attic, hanging on a cross. A friend that would repay Marcelino's kindness by granting him one heart-felt wish.
Hyacinth, a former matador who lives miserably with his nephew Pepote, receives a letter reminding him that, as agreed a few days before, he must participate in a bullfight to be held that same afternoon.
Marcellino becomes an orphan and finds two uncles--a good old eccentric man and a villain.
