Arresting Ana tells the story of the potential criminalization of the pro-anorexia movement in France. The film follows two women: Sarah, an 18-year-old college student with a ‘pro-Ana’ blog, an online forum on which she shares tips and tricks with other young women on how to become anorexic, and Valerie Boyer, a passionate legislator who is proposing a ground-breaking bill that aims to ban pro-Ana websites by issuing $30,000 fines and 2-year prison sentences to members of this online underground movement.
