In Prague, the Doctor meets Kája, a puppeteer whose fiancé, Dusan, is due to be executed by defenestration because he cut down a tree to make a puppet. Kája throws a life-size marionette off a bridge to get herself used to the idea of seeing him die. The Doctor, however, has an idea.
Kája dresses the marionette up to look like Dusan, while the Doctor uses the sonic screwdriver to set up a sympathetic vibration between the marionette and a small puppet. He takes the TARDIS to where Dusan is being held and switches the marionette for Dusan.
The marionette, controlled by the Doctor to seem life-like, is duly thrown out of a window the next day, while the Doctor, Kája and a disguised Dusan watch. Kája and Dusan will leave Prague.
