A series of short stories based on the board game of the same name, this program includes audience participation and interaction with the `Cluedo` Presenter, as well as with the `Cluedo` characters of: Mrs. Peacock (a beautiful wealthy widow), Miss Scarlet (her equally beautiful step-daughter), Professor Plum (an architect, and boyfriend of Miss Scarlet), Colonel Mustard (a retired military officer, and long-time friend of the family), Reverend Green (another long-time friend of the family) and Mrs. White (the housekeeper for Mrs. Peacock and Miss Scarlet). Throughout the program, the studio audience tries to work out the identity of the murderer, the weapon, and the room in which the murder was committed. The action invariably takes place at `Brindabella`, the stately home of Mrs. Peacock and Miss Scarlet.
