Storyline
A theater owner needs a magician to replace one that has disappeared. A booking agent sends over a gentleman who makes mischief between the owner and his girlfriend. The owner wants to see the magic act and the magician obliges by making the girlfriend disappear. She was wearing a thousand-dollar string of pearls and it seems most likely that criminality is afoot. A chase begins, which gets paused as some one remembers that the show must go on, so the doors are opened and the audience enters. What follows are some dynamite musical and comedy acts including Nat King Cole and Moms Mabley.
