Anveshana (2002)

Suspenseful and scintillating, this tale of terror sparks off with Prabhakar, a bright young man, crushing himself to death by walking straight into a speeding train. While everyone believes that it was a suicide, his brother, Vamsy (Ravi Teja) is confident that Prabhakar would never do such a thing. Suspecting foul play, Vamsy decides to investigate into the true cause of death.

Vamsy's girlfriend Bhavana (Radhika Varma) seems to be affected by the harmful effects of occult practices and occasionally suffers from seizures. Bhavana is told by a priest that the only solution to the negative effects of the black magic that have been used upon her is to marry a man with a matching birth chart.

Fortunately, Vamsy's birth chart is a match and the young lovers get married. According to the priest's advice, the powers of black magic would cease to harm Bhavana only after she has been sexually intimate with her husband.

Just after their wedding ceremony Vamsy finds a couple of unopened letters addressed to Prabhakar. They have been written by a watchman of a forest guesthouse and the letters warn that Prabhakar must return to the guest house at all costs or face dire consequences.

After reading the letter, Vamsy becomes even more determined to investigate and joined by Bhavana, embarks on a terrifying and dangerous journey to expose the real reason behind his brother's death. Will Vamsy and Bhavana succeed in exposing the truth without endangering their own lives?
