What it's about:Girlboss is actually the biography of Sophia Amoruso, the founder, CEO, and creative director of the brand Nasty Gal. It's the story of Amoruso as a troubled young girl (Britt Robertson) who spends her teens and 20s hitchhiking, committing petty theft, and scrounging dumpsters . . . until she gets an idea that changes her life.
