While cleaning the windows, Dilys falls off the ladder and loses her memory, meaning Norman Price is having to do a lot of explaining. A new fire-fighter: Penny Morris comes to Pontypandy from Newtown, and Fireman Cridlington is smitten with her. Later Trevor's bus gets stuck in a ditch and has to call Fireman Sam for help.

Norman Price's double bluff backfires when chicken pox hits Pontypandy. Firefighters do training fitness in the morning hours, when there's a Fire at Pontypandy Fire Station in the kitchen.

It's Halloween in Pontypandy and Firefighter Penny Morris is in for a nasty shock.
