Their eternal wrangling causes the rare apple from the tree of the knowledge to roll on earth. And that God is really angry. Petronel with Urias find themselves in a small Czech town on the eve of the feast of St. Nicholas. And after a series of human and "divine" tests our heroes eventually find that the path to knowledge leads primarily through self discovery through the strength of friendship, love and forgiveness skills.

"I'm feeling like a dog, doctor". Mr. Ota Posta is not feeling very well lately, deprived and humiliated like a dog he turns into one.
