"Why is my son stupid?" laments the poor Roma coal miner. His son Dilino is a nice boy, but he still causes his parents a lot of worry. He hasn't picked up much sense, so he's not much use to the coal family, and he's got all kinds of crazy ideas on top of that. For example, he began to force his unfortunate father to go and ask for the hand of the princess herself for him!
Unfortunately the movie Dilino a čert is not yet available on HBO Max.
