Melinda and Jim (the form of Sam is not shown in this episode) volunteer to chaperone a school dance when the ghost of a woman appears to Melinda and asks her to keep an older boy named Tim Dwight away from her daughter Kristy Marks. The woman named Deborah Marks had recently died in an accident in her home. She is worried about her daughter's feelings for Tim who was saved from a juvenile detention center by Deborah. It is later learned that Tim was put up for adoption by Deborah while in college before she was married to her husband. Melinda helps the father and daughter cope with the death of a wife and mother explaining to them the story behind the relationship between Tim and Deborah. Tim gets a chance to say goodbye to his birth mother through Melinda.
Melinda and Jim keep setting times for a date and it gets cut short by Melinda either because of a ghost that is present or by having to investigate what happened to the ghost. In the end Jim is discouraged and tells Melinda that her heart is not in it yet because her husband had recently died. She tells him it is and kisses him and they leave for a date.
A very good episode, but it was pretty predictable that Tim and Kristy were brother and sister and they didn't know it.
