Martha works for an advertising agency, filming a TV commercial on location in Cornwall. Her boss's new client is the eccentric owner of a chemicals company that has invented a new, almost irresistible perfume, and Martha is in charge of shooting the romantic ads - unfortunately starring his difficult daughter-in-law.
In a witty parody of the classic gothic, Martha soon becomes embroiled in a conspiracy over the missing perfume formula as the increasingly incredible plot strands - which include an amorous sheikh, a series of exploding soup cans and a kidnapped baby - mount to a hair raising climax around her.
