This straightforward documentary is about Patty Schemel, the drummer on Hole’s most important contribution to the history of rock, Live Through This. Schemel is a great drummer and an excellent human being whose life has seen some serious highs and lows. Rock music sent her up to fame and money; drugs sent her right down to obscurity and poverty. The documentary tells all: her childhood, her years in Seattle, her close friendship with Kurt Cobain, her weird relationship with Courtney Love, her addiction to hard drugs, her lesbianism, and, of course, her long and hard fall from the terrific heights of Hole.
