This fluid ensemble acts out the Kennedy assassination as revealed by the iconic Zapruder film. As they perform the scene several times, the actual fuzzy-framed film is projected upstage. To say that it is affecting doesn’t say enough. It soon becomes clear that ritual is the key to this performance, especially when the action leaps backward over the millennia to the Garden of Eden, where Eve is tempted into disobedience by a snake that is composed of five actors twining together, slithering sinuously with their arms and legs twisting together, and their serpent tongues flicking in and out of their mutual mouths. And Adam is the doufus who goes along with it.
