Guru Sishyan (1988 film)

Guru Sishyan, Guru (Rajinikanth) and Babu (Prabhu) are two friends and petty criminals. They end up in jail and come across an innocent man ('Mannvaasanai' Paandiyan) who tells that his sister was raped by Muthuraaj (Radha Ravi) and killed a taxi driver with the help of foolish corrupt police officer Nallasivam (Vinu Chakravarthy) and pinned the murder on Paandiyan. Paandiyan is sentenced to death row for the killing by the court. Guru and Babu believe in Paandiyan's story and decide to find the truth and proove his innocence once they get out of jail. Guru fractures Paandiyan's hand so that his death sentence would be delayed, until it heals, under law. Guru and Babu get released from prison and set in motion an elaborate plan to find out the real killers. Along the way, Guru, who believed that his parents were murdered, finds out that they are in fact being held captive by Muthuraj's brother who is trying to find the map to a treasure. The location of the map is know only by Guru's father who is suffering from memory loss and is tortured to make him remember it. Babu finds out that his parents were murdered by Muthuraj. Guru and Babu help them find the treasure to free Guru's parents and Guru finds out that Paandiyan is his own brother. The ensuing fight at the treasure location, ends up with Muthuraj and his brother arrested by police after Guru and Babu beat them up and the treasure cave collapses after Guru, Babu and Guru's family escape from it. Babu marries Muthuraj's cousin(Seetha) while Guru marries Nallasivam's daughter(Gouthami) and they live happily ever after.
