CARRY ON SCREAMING

In the Edwardian era, in Hocombe Woods, Doris Mann and Albert Potter are courting. When Albert searches the woods for a peeping Tom, Doris is abducted by a monster named Oddbod, who leaves a finger behind. Albert finds the finger and rushes to the police station to report the matter to Detective Constable Slobotham, who in turn tells his superior, the henpecked Detective Sergeant Sidney Bung, who has been investigating similar disappearances in the same woods.

After searching the woods for further clues, the group stumble across the eerie Bide-A-Wee Rest Home, and are shown to the sitting-room by the butler, Sockett. Sockett informs the mistress of the house, the seductive Valeria, of the men's presence, and she in turn awakens her electrically charged brother, Dr. Orlando Watt. Dr. Watt speaks to the three, who are frightened from the house when Dr. Watt vanishes when his electrical charge runs down and reappears when he is plugged in.

The next day, Bung, Slobotham and Potter interview Dan Dann, a lavatory attendant who once worked at Bide-A-Wee as a gardener, but Dann is silenced by Oddbod before he can reveal anything. Meanwhile, the police scientist accidentally creates a second creature—Oddbod Junior —when subjecting Oddbod's finger to an electrical charge. After killing the scientist, Oddbod Junior makes his way to the mansion, where Valeria and Watt are turning people into mannequins to sell. Bung arrives at the house to investigate Dann's death, but becomes infatuated with Valeria instead.

The next day, Potter discovers Doris—in mannequin form—in a milliner's shop but no proof can be found that it really is Doris. Bung returns to the house and discovers evidence that links Valeria and Watt to the mannequin but remains oblivious. Believing him to be on their scent, Valeria and Watt use a potion to turn Bung into a hairy monster man and order him to steal the mannequin for them. After recovering the next day, Bung and Slobotham decide to set a trap in Hocombe Woods, with Slobotham disguised as a woman for bait. Bung's sharp-tongued wife Emily follows, thinking that Bung is having an affair, and is captured by Oddbod Junior while Slobotham is captured by Oddbod. Bung, now teamed up with Potter, makes his way to the house whilst following their footprints.

After failing to dispose of Bung and Potter with a snake, the Oddbods are dispatched to deal with them. Bung and Potter are reunited with Slobotham and manage to return Doris to human form, but discover that Emily has been turned into a mannequin. A battle follows, in which Albert (in monster form) defeats the Oddbods. Dr. Watt menaces them with petrifying liquid but is threatened by the re-animated mummy of Rubbatiti, who has come alive following a lightning strike. Rubbatiti and Watt fall into a boiling vat in the cellar, killing them both. Albert and Doris marry some time later, and discover that Bung, whose home lacks electricity, is unable to return his wife to human form, and is now living with Valeria.

Dr. Watt and the mummy Rubbatiti perish in a boiling vat after a chaotic battle, Doris is restored, and Albert marries her. Bung is left with his wife transformed into a mannequin due to a lack of electricity at home.

The film’s finale wraps up its array of madcap horror send-ups with a characteristically absurd twist—heroes are victorious, villains are dispatched in over-the-top fashion, and the bumbling Bung faces a domestic dilemma straight out of farce. The ending underscores the series’ affection for irreverent parody, leaving everyone exactly as silly (or unlucky) as they began.
