It's 40 years this month since 30,000 women 'embraced the base' at RAF Greenham Common, Berkshire in protest at the proposed siting of cruise missiles there. For some of them, the Women's Peace Camp became home and the RAF base the scene of countless actions, as political convictions led inevitably to arrests, court appearances and imprisonment.

Lyn Barlow served something between 15 and 20 sentences - she lost count - and Sue Say at least eight. Mild-mannered former teacher Mary Millington has journals documenting her numerous prison terms. Greenham Convictions traces why these women put not just their bodies but "their entire beings" on the line for a cause - and at what price.
