February 1948. The struggle of decisive social forces for the heart of Europe.

Once upon a time, there was a kingdom where a spoiled and conceited princess lived. She didn't like frogs and other similar vermin, so she didn't like it very much when they suddenly started jumping on her from everywhere. In the local pond, there lived a waterman whose water machine for water lilies broke down. Instead of beautiful flowers, he produced croaking frogs. However, the waterman didn't like the princess's behavior at all and as punishment, he made her speechless. She can only be freed if she kisses the frog. So the prince and the young diver enter the story to put everything in order. Will the princess kiss the frog? And who will finally earn the improved princess as his wife?
