Melinda Gordon communicates with earthbound spirits, ghosts who cling to the living because they have unfinished business that prevents them from moving beyond the familiar plane of existence that we call life. A fair bit changes during that leap, including Jim having become a doctor, but much has not: Melinda stills sees and hears spirits, and still tries to shepherd them to the light. Among the cases that come her way: a chain e-mail that comes with a malevolent force attached; a haunted hospital morgue; and a radio station that broadcasts a mean-spirited skit thanks to the interference of a vengeful ghost.
