With his new and demanding job as Head of SDS, it's Postman Pat as you have never seen him before. This well-deserved promotion means that Postman Pat will now be called on by the SDS to deliver anything, anytime, anywhere.
It's Christmas Eve and the children have made Secret Santa presents for the Christmas party in Pencaster Square. The giant stocking that was to deliver the presents rips open and several presents are lost. It's up to Pat to find and deliver the presents.
