When Annie's husband John dies of leukaemia, she and best friend Chris agree to raise money for a new couch in the local hospital waiting room where they spent so many uncomfortable hours. They manage to persuade fellow WI members to pose nude with them for an "alternative" calendar, with a little help from hospital porter and amateur photographer Lawrence.
The news of the women's charitable venture spreads like wildfire, and hordes of press soon descend on the small village of Knapeley in the Yorkshire Dales. The calendar is a success, but Chris and Annie's friendship is put to the test under the strain of their new-found fame.
Based on the true story of eleven WI members who posed nude for their annual calendar to raise money for the Leukaemia Research Fund, Calendar Girls is a raucous comedy about friendship, determination and hope.
