Melinda encounters the ghost of a bipolar woman, Tammy, who it's assumed had run out on her husband, Roger, and who had been missing for two years. Melinda and Eli work under the theory that Tammy's mental condition had contributed to her rash decision to leave Roger, and after help from a vision they find Tammy's dead body in her car, where it appears that she committed suicide. This leads to the discovery that Tammy had not only run out on Roger, who had remarried, but also on her previous husband, Thomas, and their two boys. Tammy tries to help Melinda figure out exactly what led her to this end, but she struggles to remember anything about her life. However, after Melinda notices bruises on Tammy's wrists it all comes flooding back. Roger had kidnapped and brainwashed Tammy, eventually convincing her that she was his wife and that she loved him. When he felt he was starting to lose control over her he decided he had to kill her, so he drugged her and staged the suicide to cover his tracks, and then he repeated his crime by kidnapping his current "wife." Melinda is able to rescue this latest victim and reunite her with her family, and she helps Tammy reconnect with Thomas and her sons before crossing over.
