In the Prague Old Town and the adjoining streets there is always plenty of life. Housewives shop, beggars arouse sympathy, the Salvation Army tries to put the godless on the road to salvation by hymns and sermons, and Ferdys Pistora hunts in the pockets of his fellow men and isn't even put off by the presence of an officer of the law. Ferdys sets off to burgle villa of the banker Rosenstok, but a fire breaks out in the house and Ferdys ends up saving the banker's two small children. For this he is celebrated as a hero and gets a place as an errand boy with the Rosenstoks. At home he is visited by representatives of the Salvation Army, Captain Kosterka and Terezka, with whom Ferdys instantly falls in love.

“And I say unto you, ask and it shall be given to you; seek, and ye shall find; knock, and it shall be opened unto you”. This quote from the Gospel of Luke is read out loud by one of the characters in Tam na horách. It will manifest itself in the destinies of the two protagonists, in the story of an unmarried mother from a mountain village, who becomes a great opera singer and toast of the city salons, and in the story of her seducer, a successful painter. The fate of the two lovers offers a double perspective. One of the advertising slogans for Tam na horách was “The first Czech film of international production”, which helped to rise the audience’s expectations.
