Buffalo-based filmmaker Meg Knowles retraces the steps of her sister, who in the summer of '73 ran away from an upscale New England summer camp, hitchhiking cross-country to California. Weaving a tale of teen angst gone off the rails, a mother’s patient desperation and a sister’s disbelief, Knowles’ warm, personal documentary begs the question: does retracing your steps heal old wounds or make new ones?
