The document discusses plot, or the "spine", of a story. It states that the plot is the central conflict or problem driving the narrative forward. It provides examples of classic stories where the spine is a character's quest (Moby Dick) or desire (Gone with the Wind). The author argues that the plot is typically defined by what the main character wants most and how they try to obtain it, creating narrative tension. The document then examines the spines of the author's own novels, which revolve around a character longing to forgive themselves, gain freedom from enemies, or free themselves from oppression.
