It's Halloween and Fireman Sam gives Norman the biggest pumpkin in the pumpkin patch so he can make a Jack 'O Lantern. Norman is determined to go all out for scares and leaves his lighted lantern unattended while he takes to the streets as "Count Norman, the scariest vampire in all of Pontypandy". While he is trick-or-treating at the fire-station Norman discovers his mum's shop is on fire and she's inside.
