unfinished business become earthbound and cannot cross over, and Melinda, as their earthly representative, helps them to find peace. The show does not present the ghosts as having sinned; rather it is the spirits' own guilt that condemns them, and their own fear of judgment that keeps them from "crossing over" into an afterlife.

The series also starred Aisha Tyler as Andrea Marino, Melinda's best friend, who runs the antique shop with her.
