København, Kalundborg og -? Aug 20, 1934

Ludvig Brandstrup is a radio announcer and performs with great experience in front of the microphone. But the director is not exactly taking care of his duties; he has forgotten to inform the artists who will assist with the broadcast. This forgetfulness is a very serious blunder. On top of that, an award-winning radio play, "Where is Jensen?", is to be broadcast, and now the actors are missing. Brandstrup is desperate and distraught, until he gets the bright idea to play all the roles himself.
