Hotel - Season 5 Episode 13 Double Take

An Elegant matron, Barbara Lyman, swears she's marked for death because she witnessed a murder in the hotel that nobody else can prove really happened. Despite two more terrifying encounters with the killer, Barbara can get little help from Billy or Inspector Chin. The so-called killer turns out to be her husband, who often appears as the villain in Barbara's paranoid hallucinations. Peter books his favorite country singer, Joe Daniels, to perform in the hotel nightclub. Joe's career has deteriorated from alcohol, but he is starting a comeback after a five-year absence. His 18-year-old son Mark, who has his own drinking problem, is disappointed when his father hits the bottle again. Joe's ex-wife Lisa is there too, and tells Joe about his son's developing alcoholism. On opening night, Joe is surprisingly sober, giving them the hope of reuniting as a family.
