Kevin reluctantly agrees to host a last-minute Halloween party despite the fact that he's had no time to prepare. Meanwhile at the school gates the mums are all talking about a celebrity who has moved into the neighbourhood - Lee Mead from Holby.
As this is Julia's favourite programme she is determined to meet him and decides to take all the kids trick or treating hoping that they will find his house. Liz tags along as she has been stood up by a date and Anne is in attendance trying to make sure that the kids are safe. However by the time they reach Kevin's one of the kids is missing - Amanda's little boy Manus. Despite the fact that the happy teatime trick or treat atmosphere has now turned violent and terrifying Liz, Kevin and Julia must venture back out into the streets to search for him through terrifying hordes of teenage zombies and mutant nuns.
