It is winter of 1922, on the evening of the engagement party between Charles Haversham and Florence Colleymore. A few hours into the party, Thomas Colleymore - Florence's brother - and Perkins - Charles' butler, head to the lounge to check on the groom to-be, only to find him dead by unknown causes. After benefitting from a large and sudden inheritance, the inept and accident-prone Cornley Polytechnic Drama Society embark on producing an ambitious 1920s murder mystery. They are delighted that neither casting issues nor technical hitches currently stands in their way. However, disaster ensues and the cast start to crack under the pressure, but can they get the production back on track before the final curtain falls.
