One year ago, Honey’s (Alice Eve) dear husband was murdered at her annual Halloween Costume Party. Honey has vowed she will not rest until she can seek vengeance upon the murderer, but a year has passed since the horrible event and she’s no nearer to solving the crime. Covertly, Honey hires a Police Inspector (Wilf Scolding) to attend this year’s party - to which all the potential suspects are invited - and unmask his killer.
