Ghost Whisperer Episode 3.07 Unhappy Medium

Famous author and medium Casey Edgars comes to Grandview to help a family, the Drakes, find their missing daughter, Sydney. Melinda meets Casey and immediately pegs him as a fraud when he fails to notice a mysterious spirit attached to him. Casey insists he is led by spirit guides and assures the Drakes that Sydney is alive. However, Melinda discovers that the mysterious ghost is actually Sydney, who demands that Melinda get Casey to tell the Drakes the truth, that she is actually dead. When Melinda passes this information on to Casey, he refuses to believe her. For each to prove what they believe to be true, the two decide to work together to discover the real truth, and they collaborate to find Sydney's dead body in a remote part of the woods. Now involved in a murder investigation, the pair continue to investigate, and eventually they discover that Sydney had been suffering form a drug addiction. Sydney's sister, Nikki, and her boyfriend had tried to break her addiction by kidnapping her and forcing her to go cold turkey against her will. Unfortunately, Sydney escaped from the remote cabin where she was being held and got lost in the woods, where she died. At Sydney's request, Melinda and Casey pass this on to the Drakes, and when she's sure that Nikki won't be blamed for her death, Sydney crosses over.
