A poor student named Matthew arrives Prague to study with Master Hanuš [cs].

Jemmy ends up causing the scaffolding on a side of the bridge to fall due to his carving of a statue of Katie from a support beam.

Hanuš wants to take revenge for this violence, and ruins his own astronomical clock by sabotaging the gears.

Jemmy, as his assistant, is commissioned to fix the astronomical clock under Katie's threat being executed if he fails to do so in time.

Jemmy fixes the astronomical clock at the last minute but arrives at the gallows too late, and Katie has been hanged already.

As the goat falls from the gallows, it is revealed that she had an iron tube in her throat the whole time, and it meant her neck was never snapped and survived the hanging.
