Once upon a time there was a single father and his son. Every day, the father was overprotective and worried about his boy. One day the boy went out on his own, and got kidnapped. Because of that, the father went on a quest to find him. Because of that, the father had a lot of new experiences, met lots of new and different people, and realized what was important in life. Until finally he rescued his son, and they lived happily ever after. I'm sure you could write it up other ways, and do a better job with more time, but basically, that's Finding Nemo.
