CALENDAR GIRLS is based on the true story of a group of women who bare all - or nearly all - for charity and become international celebrities as a result.

The Women's Institsute, in Great Britain, encourages the ancient skills of jam-making, flower pressing, knitting and baking. So when a group of extraordinary women are looking for a new way to raise money, they decide to take the annual WI calendar, normally featuring landscapes or flowers, and create something traditional - but with a twist.
