Ghost Whisperer Episode 1.13 Friendly Neighborhood Ghost

While a man moves in across the street from Melinda, she notices that presence of a ghost as well. He turns out to be the father of her neighbour's former girlfriend, who disappeared and is presumed dead.

Her father promised to not rest until he finds out what happened to his daughter and therefore haunts the man day and night. Melinda finally gets through to both of them and then they learn that the girl is not dead at all, but simply ran away from the very strict regime her father made her live in after her mother went away. In the end, everyone finds peace.
