It was high summer and a travelling fun-fair had come to the village... Peter Rabbit and Benjamin were forbidden to attend. But even the best-behaved rabbit can't keep away from a fun-fair; and Peter is far from being the best-behaved rabbit.

With Benjamin at his side, Peter sneaks into the fair where a roller-coaster ride of an adventure begins... When Peter finds himself scooped up by a rather grumpy little girl and separated from his cousin he is helpless and very afraid.

It takes the determined bravery of Benjamin to rescue Peter from the frightening hurly-burly of shouting stallholders and whirling rides.
