Powder and Petrol

At a crossing in Prague being supervised by an incompetent policeman, a sight-seeing bus driven by an equally incompetent driver, crashes into a taxi in which the actress Marta is arguing with her boyfriend, composer Jiří David. The policeman and the driver take a fancy to Marta so they invite her out on an excursion in the bus. The excursion is not too successful but, to make it up to Marta, the two men take the girl to an evening boxing match in the Eden club. Here the policeman and driver cause a great disturbance which ends in a fight between the policeman and the defeated French champion. Jiří has written a grand musical-hall number for Marta which requires two comics. The librettist remembers the two nutty men at the boxing match and recommends that they be included in the cast. Both new comics enjoy great success and, furthermore, contribute to the disposal of a gang of drug dealers whose leader had been blackmailing Marta's brother. It is only in love that they are unsuccessful, however, when they see that Marta prefers her Jiří.
