Set in the breathtaking valley of Spiti in Himachal Pradesh, Paap is another example of Bollywood's fascination for adapting Hollywood films within an Indian context.
Under her father's strict rule, Kaaya (played by newcomer Udita Goswami) has been brought up in an atmosphere of religion and physical denial. When her father urges her to join a Buddhist monastery, Kaaya is assigned to bring six-year-old Lamo (Madan Bhiku) from Delhi to the monastery in Himachal Pradesh, where he is to be received as the reincarnation of a great Lama. However, during their stay in the city, young Lamo witnesses a killing and the couple find themselves fleeing to the holy sanctuary under the protection of city cop Satyen (played by John Abraham). Satyen himself is on the run, having discovered that the murder witnessed by the young Lama is linked to dangerous officials in his own department. Thrown together amid so much danger, against her father's wishes Kaaya finds herself falling in love with Satyen.
