Dr Smith discovers an enchanted harp. When he plucks the strings he is transported to a fiery underground cave. There he is greeted by a man in a red suit who asks him “Where in the devil do you think you are?”
The Lucifer-like character says his name is Morbus. He shows Dr Smith a massive book that lists his name. Morbus compels him to watch a video screen that takes Smith back to his own childhood days. The young Dr Smith is shown to be a ‘snitch’, a thief, a liar and a ‘cake stealer’.
His ‘Infernal Majesty’ asks Smith to destroy the harp. If he does this Morbus will grant him a second chance. Dr Smith agrees and promises to turn over a new leaf. Meanwhile Morbus transports himself down to the planet the Robinsons are living on. Smith realizes if he plays certain notes on the harp in a particular sequence Morbus feels pain and can be controlled.
Morbus transports himself and Judy back to his cave. He reveals he is a prisoner there and only when the harp is destroyed will he be free. John and Don go in search of Judy. During a fight between Morbus and Don the harp is broken. Morbus’s prison doors open and he is set free to continue his mischief in regions (car-parks included) throughout the galaxy.
