Welcome to Papaya Island! A remote place full of weird traditions where each kid gets a baby bull to be their best friend and caretaker. Every child on the island pairs up with his or her bull from the moment they are born until their teenage years… Except for Cacupé, a foreign boy who mysteriously arrived on the island, and, after being very insistent, got his own bull who he named: Sócrates, a neurotic, know-it-all bull who nobody wanted. And, haphazardly, this unlikely couple will start to challenge all of Papaya Island’s habits.
