The indebted owner of the Dubanský chateau sees the only way out of his debts in marrying his daughter Jana to the son of his childhood friend Bernard, now a millionaire. Without knowing each other, the young people are both against an arranged marriage. Dubanský himself marries a con artist who pretends to be a rich American and takes her on a honeymoon to the Tatras. In the meantime, the enterprising staff rents out the chateau under the name Bílá vrána to spa guests.
