Angelína is not interested in poor Petr while Adélka falls in love with him and tries to help him.

Janek accidentally joins the army and loses his supernatural powers when soldiers burn his wolf's tail.

Petr works in Hell and Lucipher eventually decides to release him and fulfill him three wishes.

Petr's wishes are: a magic coat that produces golden ducats, a release of his grandmother and permission to take the Corporal to Hell.

When Angelina sees him she changes her mind and wants to marry him but Petr declines and states that he asked for Adélka's hand.

The film is loosely based on Čertův švagr by Božena Němcová.
