Computer animation. Pat offers to take Alf's racing pigeon for a check-up while delivering the mail. A flood on the main road means Pat has to take the winding road through the hills. He runs out of petrol, and Pat and Jess get stranded for the night. Night draws in and the villagers still haven't found Pat. The following morning Pat has the idea of using Alf's racing pigeon to carry a message asking for help.
