A young nameless poet (Dieterle) enters a wax museum where the proprietor works in the company of his daughter Eva (Olga Belajeff). The proprietor hires the poet to write a back-story for his wax models of Harun al-Rashid (Jannings), Ivan the Terrible (Veidt), and Jack the Ripper (Krauss) in order to draw an audience to the museum. With the daughter by his side, the poet notices that the arm of Harun al-Rashid is missing and writes a story incorporating the missing arm.
