A certain gentleman now referred to as Doctor Bat causes chaos at Prince Orlovsky's masked ball. Errant husbands are sentenced to imprisonment, wives itch to betray their husbands and budding starlets appear in disguise. The hijinks and partying end up in a prison yard, but this is where the laughs really start! This champagne-fuelled full-length opera is Johann Strauss's masterpiece and without doubt the crowning event of the winter holidays. Doctor Bat and his friends have one hell of a New Year's ball in store!
