Three twelve-year-old girls carry small video cameras into their own bedrooms for a year, recording diary-style confessions that filmmaker Victoria King weaves into the finished film alongside footage of their daily lives at home and school. The girls talk through friendship fallouts, first crushes, and arguments with parents in their own words, giving the film an unfiltered register that standard interviews rarely produce. King's camera also follows the adults around them, tracking how family routines and expectations shape each girl as much as, or more than, what her classmates think of her. The film stays close to three specific households rather than generalizing about adolescence, letting differences in each family's approach to rules, privacy, and independence show up in the girls' own accounts of their year. It ends at the edge of thirteen, with the diary-cam footage as the closest thing to evidence of what actually changed. Made in 2006, it works as a document of one narrow, specific age rather than a broader theory of growing up.
