One morning, the criminal authority Dad convenes three sons and tells the latest news. Everyone remembers how three years ago, the keeper of the regional communal Mule ran away, taking the money. Also, everyone remembers how he was found, punished and buried. And the news is like this. Yesterday Mulya, alive and well, was seen in three cities at once St. Petersburg, Novosibirsk and Rostov. Dad sends sons to these cities to scout out whats what. For each of them, the journey will not be the easiest.
