Many times Shaun is shown as the only intelligent sheep in the flock.....but that is not so, as we see in this humorous episode.
The farmer has a narrow swimming pool and it's hot outside....really hot, with everyone looking to cool off. When the animals, including faithful dog Bitzer, see the farmer going out to cool off in his pool, it kills them. They want to do the same! Bitzer, being the good employee he is, will not let the sheep enter the pool. Therein lies the big premise to this animated short: how can the sheep get into the pool?
The methods the sheep use trying to get into that pool are very, very funny and make this another solid entry in the "Shaun The Sheep" series. These sheep are pretty clever and some of the sights you'll see will have you laughing out loud a number of times. (Start by beginning to picture a sheep with snorkel and swim fins!)
