Armaan's life is picture perfect; a loving girlfriend, a fabulous job as a fashion photographer, and yet, things aren't as perfect as they seem to be. A chronic patient of insomnia, his sleeplessness is not a function of any sleeping disorder. The truth is that he hears voices; voices that torture him, voices that don't let him have his peace, voices that nobody else can listen to. While his friends sympathize with his problems, his girlfriend Gehna is irritated with his weird behaviour, and her father constantly berates him for his fondness for the bottle. No one seems to understand his predicament. What puzzles everyone is the fact that he talks to himself...or rather, he talks to people whom no one can see, simply because they don't live. Suddenly aware of his special ability to connect with the souls that haven't crossed over and equipped with a will to fulfill the wishes of the spirits that hound him, Armaan now sets out on a mission to help three souls - a child Ali, an old man Mr. Kapoor, and a young woman Carol. The exciting journey that follows, where Armaan discovers the lives of his three special companions, and a lot about himself and his life, is the crux of the plot of 'Hum Turn aur Ghost'.
