Remaining at home with his father-a doctor at the hospital for the poor-Marco cannot help but miss his mother. When Anna suddenly stops writing to them, Marco becomes anxious about her and decides to travel all the way to Argentina by himself. Marco sets out a long and arduous adventure of over 10,000 miles. All he carries with him is love, courage, friendship and a longing to see his mother again.
