In Stick Fly, conflicts over race, class and privilege simmer and then boil over. Lydia R. Diamond’s comedy-drama, set in the luxurious Vineyard summer home of a prosperous African-American family, stirs the domestic pot when the two sons show up with their new girlfriends—one white and wealthy, the other black and not. Another young woman forms a third rung on the social ladder—the maid.

To that uneasy mixture, add another family tension: one of the sons is a successful plastic surgeon, but the other is a drifting would-be writer and a disappointment to their father.
