Three-part documentary about the Women's Institute as it finds its way into the 21st century, revealing the lives of a formidable group of women holding communities together across Britain. In the Yorkshire Dales, the ladies of Gunnerside WI are preparing something special to celebrate their 60th year. Group treasurer Janet, a dynamic businesswoman, wants to lead them out into the surrounding countryside with an ambitious day of outward-bound exercises entitled One of our Sheep is Missing. Retired school-teacher, Mary, lives and breathes the WI. She used to be an active member of Gunnerside WI, but ever since she was passed over for the presidency she hasn’t been to a meeting. In an attempt to bring Mary back into the fold, Janet tries to get her involved in the celebrations. But Mary has serious reservations and their differences of opinion lead to an unforeseen outcome.
