Seems that wealthy and prominent members of the community have been executing crimes and then forgetting that they ever happened. Eventually the District Attorney and The Green Hornet find that Peter Eden, owner of the Vale of Eden, has been leaving ""suggestions"" in these people's subconscious dreams after receiving treatments from the Vale of Eden.

Part two picks up with a GREEN HORNET visit and proposition for Peter Eden, owner of the Vale of Eden. After Peter uses Vanessa Vane to double-cross the Hornet, the Hornet re-visits Peter and uses his own dream machine on Peter to foil the last crime for the evening.
