Kym is a former model. Kym is in rehab. Kym's family is well heeled but extremely dysfunctional. Kym is responsible for a horrible tragedy that no one will talk about. Her sister, Rachel, is about to be married, and Kym is granted a leave to attend. Kym wants desperately to fit in, to be a normal person, but she doesn't know how. In her slouchy dark clothes, with a choppy, angular haircut, she seems programmed to shut everyone out. Kym, as a participating member of the wedding, finally comes to understand that giving up a certain amount of control in the interest of a mutual good is a fair definition of the state of marriage, and sometimes, you have to take the risk and see what happens, for better or for worse.
