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.
