Chris and Annie are the best of friends - very different, but very close. Living in a small village in the Yorkshire Dales, their peaceful lives are shattered when Annie's husband dies of leukaemia. An active member of the local Women's Institute, Chris enlists the support of her fellow members in a fund-raising initiative for the local hospital. Her seemingly traditional idea is to produce a calendar, with a different woman photographed for each month. Each one will be engaged in a classic WI task, such as jam making, flower pressing and knitting. Sounds traditional enough, but her idea has a radical twist - the women will be in the nude. Before they know it, the women are hitting the headlines at home and abroad. Whisked off to Hollywood on a whirlwind publicity tour, they take their turn on the talk shows and in magazine photo-shoots. Amidst the hype and glamour, the friendship between Chris and Annie is put to the test.
