Bobo is Indias leading magician. But unknown to even his girlfriend Tamara, Bobo’s life is falling apart. His constant hallucinations leave him with no option but to seek psychiatric help. When he is put through regression hypnosis, a terrifying childhood story surfaces, in which a sinister power (daayan), which has destroyed his family, promises to return to haunt Bobo. Bobo ignores it and moves on with life. His romance with Tamara is at full throttle and his career as a magician reaches great heights. The going is good till the irresistible Lisa Dutt enters his life. He is convinced that she is the daayan. But is she, really? Or is Bobo just losing his mind? An entertaining romantic thriller with an electrifying jolt at the end, Ek Thi Daayan marks the first ever association of two creative powerhouses – Ekta Kapoor and Vishal Bhardwaj.While it is Balaji’s third outing with Emraan Hashmi (after Once Upon A Time In Mumbaai & The Dirty Picture), it is the maiden combination between Emraan Hashmi and Vishal Bhardwaj, which promises explosive, chartbusting music. Hashmi’s new avatar as a magician coupled with the film’s theme gives Ek Thi Daayan an additional invaluable appeal to children.
