The Ghost Whisperer: The Collector

Melinda is intrigued when she meets Gabriel, another Ghost Whisperer with the same abilities, but there is something about him that he doesn't trust. She becomes worried when she learns that there are ghosts attached to him, and more concerned when she learns Professor Payne's wife is dead. His wife tells Melinda the ghosts are planning something and it's bigger than just Gabriel's group. Melinda manages to help an airline attendant cross over despite the ghosts trying to block the light.
