Amanda accidentally helps Kalas escape from prison by trying to do MacLeod a favor and kill Kalas for him. After an attempt on Maurice's life thwarted by MacLeod, Kalas kidnaps Amanda to use as bait against MacLeod, but Amanda manages to escape. Meanwhile, Christine Salzer, the widow of a Watcher killed by Kalas (in ""Methos"") decides to get her revenge on Immortals and Watchers alike by exposing their secret to the media. Dawson and Methos team up to try and talk Christine out of it, but she's determined to take a computer disk with the identities of all known Immortals and Watchers on it to a newspaper publisher. Dawson, desperate, tries to kill her outside the newspaper building, but is stopped by MacLeod and Methos. Christine enters the building and the Immortals and the Watcher know their lives are about to change forever.
