Chris Rock, a man with two daughters, asks about good hair, as defined by Black Americans, mostly Black women. He visits Bronner Brothers' annual hair convention in Atlanta. He tells us about sodium hydroxide, a toxin used to relax hair. He looks at weaves, and he travels to India where tonsure ceremonies produce much of the hair sold in America. A weave is expensive: he asks who makes the money. We visit salons and barbershops, central to the Black community. Rock asks men if they can touch their mates' hair - no, it's decoration. Various talking heads (many of them women with good hair) comment. It's about self image. Maya Angelou and Tracie Thoms provide perspective.

In 1958, in New York City, the upper class Diane Arbus is a frustrated and lonely woman with a conventional marriage with two daughters. Her husband is a photographer sponsored by the wealthy parents of Diane, and she works as his assistant. When Lionel Sweeney, a mysterious man with hypertrichosis (a.k.a. werewolf syndrome, a disease that causes excessive body hair), comes to live in the apartment in the upper floor, Diane feels a great attraction for him and is introduced to the world of freaks and marginalized people, falling in love with Lionel.
