Carly has one love, sports. Years go by, and she has injured herself, and it was one of the worst places ever, the knees. BOTH of them. She worries so much about them that she can hardly enjoy sprts without worrying about her knees, or the strengthening she has to do for them. Will she be able to let that go in order to enjoy sports like she used to? Will she ever be able to find a way to save her knees?
