What good is this? How is this better than being in prison?
The exposition of Knight's Tale is when King Creon and Duke Theseus are on a battlefield and Creon loses. Two young knights are injured on the field and we learn their names, Arcite and Palamon. They are put into a tower as prisoners.
The inciting incident is when Duke Theseus´s stepsister, Emily, comes to visit. Arcite and Palamon see her in the garden through a narrow slit and start arguing about who loves her.
My blessing on you both!
The cousins keep fighting over Emily. The gaoler says Arcite is free to leave the tower because he has a friend in Athens. If Arcite comes back, he will be killed. Palamon remains in the tower. Arcite longs for Emily, so he grows a beard to disguise himself and works as her servant. Palamon escapes the tower and sees Arcite. They both start fighting in the woods until the Duke comes and says he will hold a joust between them.
The climax is when Arcite beats Palamon in the joust Duke Theseus has set up for them to win Emily's hand, but his horse trips and Arcite falls onto his lance and dies.
Palamon is upset to have killed his cousin and regrets their fight. Duke Theseus keeps mistaking Palamon for Arcite. Emily says she doesn't want to marry him because his hair is thin and she doesn't like his mouth. Her voice sounds like a clicking comb.
