Mabel Muttley, the 109 year old primary school pupil . . .
When the local theatre is looking for extras for a play, Old Buttspry School pupils are the first to volunteer and Mabel gets the part of a bee. But Sidney Scrimshanks is jealous and he comes up with some mean pranks to make sure that Mabel does not enjoy her big performance. It is all down to Mabel to steer clear of tricks and still enjoy the first night.
