At the beginning of the play, Edgar, disguised as Mad Tom, encounters his father, Gloucester, who has been blinded. Maintaining his disguise, he leads the old man off as the two go together to Dover. Goneril begins to plot against Albany, who chastises her for her treatment of her father. It is revealed that Cornwall is dead, which would give Regan freedom to pursue Edmund, whom Goneril also loves. This becomes a very divisive force between the two. Cordelia takes command of the French army poised to attack the forces of Lear's enemies. Gloucester, led to Dover by the still-disguised Edgar, meets Lear there, who has gone mad. They encounter Oswald, Goneril's lieutenant, who is carrying a letter outlining her plot with Edmund to kill Albany. After a dispute, Edgar kills Oswald and takes (and reads) the letter. In the final act, Kent brings Lear to Cordelia, where he is reconciled with his daughter. Discovering that a battle is imminent, Kent says he will cast his lot with the King.
