Emilia has been going to ballet classes for a few years to please her mother. But she is rather half-hearted about it herself. It's too bad that a performance is about to take place. The ballet class is to perform a dance to a waltz, but Emilia's sense of time is very limited. Max asks the maestro for help. He shows him how to train Emilia to improve her tact. But by the time of the dress rehearsal, Emilia has not managed to get her dance into the three-four time of the waltz. Maurice's idea of wearing a Bluetooth earpiece while dancing initially proves to be ingenious, but when Emilia loses it on stage, she also loses the beat.
