“The summer I killed my father, I was ten years old . . .” So begins Kasi Lemmons’s spellbinding feature debut, an evocative journey into the maze of memory, steeped in fragrant southern-gothic atmosphere. In 1960s Louisiana, a young girl (Jurnee Smollett) sees her well-to-do family unravel in the wake of the infidelities of her charming father (Samuel L. Jackson)—setting in motion a series of deceptions and betrayals that will upend her world and challenge her understanding of reality.
