It turns out that the disappearance of Edith Day is the lastest in a series of kidnappings and burglaries. Margo, worried for her friend, goes to Lamont Cranston for help. So The Shadow, now convinced that the kidnapper must be coming in to the houses from underground, goes to the Day mansion to find out where the missing people are and if they're still alive.
