In a modest, small-town community hall, five people – mostly strangers – come together to take part in an amateur acting class. The class is run by Marty (Gibney), a well-meaning, passionate and provocative teacher who leads the group in a series of drama games. She intends to get them in touch with their inner selves and let their imaginations run free. But as the exercises build in intensity and their lives become further intertwined, real-life drama begins to seep into the curriculum.
