Ghost Whisperer Episode 3.01 The Underneath

After a near-death experience in which she speaks with her father, Melinda is determined to learn the truth about both him and her alleged brother. First, she turns to her mother, who refuses to speak about the past. Soon after, she encounters a ghost who was killed 25 years ago in a street cave-in caused by a gas explosion that ripped apart the town square. This ghost blames Melinda for the death of his wife, and when a confused Melinda investigates this in the town archives, she discovers that her mother was actually a resident of Grandview and was indeed at the site of the accident. Furious that her mother would keep this information from her, Melinda confronts her and discovers that while her mother was trying to help the newly dead man communicate with his wife right after the accident, a second explosion killed the wife. The whole experience was too much for Melinda's mom, who moved away and ignored her gift from then on. Melinda realizes that the ghost has confused herself for her mother, thus he holds Melinda responsible for his wife's death. Melinda helps the ghost understand that his wife's death was an accident, which allows him to reconnect with his grown daughter and cross over.
