What Happens in Kudiyirundha Koyil: Full Plot Summary

The whole story of Kudiyirundha Koyil (1968) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Twins Sekhar M. G. Ramachandran and Anand Major Sundarrajan, along with their mother Mangalam Pandari Bai, witness their father Ramnadhan being murdered by Nagappan M. N. Nambiar, an escaped convict Ramnadhan had testified against. This prompts the family to leave for Madras to pursue a new life. But when Sekhar gets down from the train to fetch some water, it leaves without him. Nagappan arrives and kidnaps Sekhar, who is raised by him as a criminal. Sekhar remains unaware that the same man killed his father.

Years later, Sekhar, who now calls himself "Babu," is an established criminal and is the most wanted man in the city. Meanwhile, Anand is a club-dancer and neither he nor Babu are aware of each other's existence. During a police encounter, Babu is grievously wounded and seeks shelter in Mangalam's house, although he does not recognise her as his mother. He develops a soft corner for her, but when Nagappan (now known as Boopathy, the owner of a cabaret and employer of Babu) learns about this, he tries to erase the kindness from Babu.

During another police encounter, Babu is again wounded, but becomes insane this time, also becoming amnesiac. D. I. G. Mogan comes across Anand, and after seeing the striking resemblance between him and Babu, advises him to act as Babu to get all the secrets of the gang and have them arrested. Anand agrees, but later realises Babu is his brother. Anand's girlfriend Jaya Jayalalithaa J sees him having a lot of money in a briefcase, and the police chase him. Mangalam also learns of this, and becomes heartbroken. However, Mangalam and Jaya soon reconcile with Anand after learning of the truth, and they also learn that Babu is his brother.

Babu's girlfriend Asha Rajasree discovers that Anand is impersonating Babu, but he surrenders to her and explains about Babu's medical condition, subsequently revealing himself as Babu's brother. Asha forgives him and the duo subsequently team up to defeat Nagappan and his men. Babu later escapes from the prison to kill Anand when learning about him, but is cornered by Mangalam, who makes him realise that he is her son and Anand is his brother. Remembering that Nagappan killed his father, he teams up with Anand to defeat Nagappan, who is later arrested. Subsequently, Babu returns to being "Sekhar," and reunites with his family.

Kudiyirundha Koyil Plot Explained: Your Questions Answered

The questions people ask most about Kudiyirundha Koyil (1968): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why did Nagappan kidnap Sekhar during the train journey?

Nagappan kidnapped Sekhar to exact revenge on Ramnadhan, the twins' father who had testified against him in court, leading to his imprisonment. By taking Sekhar, Nagappan not only hurt Ramnadhan but also raised the child as a criminal, twistedly making the son into the kind of man the father would despise.

Foreshadowing: The murder of Ramnadhan by Nagappan earlier establishes the vendetta that drives the kidnapping.

  • Nagappan
  • kidnapping
  • revenge
  • Sekhar childhood
Q2

Why did the police choose Anand to impersonate Babu?

D.I.G. Mogan noticed the striking physical resemblance between Anand and the notorious criminal Babu. Recognizing this opportunity, Mogan recruited Anand to infiltrate the gang by posing as Babu, hoping to gather intelligence and bring the criminal network to justice from within.

  • Anand
  • impersonation
  • police
  • Babu
  • undercover
Q3

Why did Babu lose his memory after the second police encounter?

Babu sustained severe head injuries during the second police encounter, which left him both physically wounded and psychologically traumatized. The combination of these injuries caused him to lose his memory entirely, resulting in madness and amnesia.

Foreshadowing: His first grievous wound during the police encounter already set the stage for declining mental state.

  • Babu
  • amnesia
  • memory loss
  • injury
  • police encounter
Q4

Why did Nagappan try to remove Babu's kindness toward Mangalam?

Nagappan, now operating under the alias Boopathy, employed Babu in his criminal enterprise and cabaret. When he discovered Babu had developed a soft spot for Mangalam, Nagappan deliberately worked to eliminate that kindness because compassion could compromise Babu's loyalty to the criminal network and hinder their operations.

Foreshadowing: Boothapathy's cabaret was established as Babu's place of work, where his criminal ties were strongest.

  • Nagappan
  • Boopathy
  • Mangalam
  • kindness
  • criminal loyalty
Q5

How did Anand discover that Babu was his twin brother?

Anand learned the truth when he was already impersonating Babu. The revelation came when Mangalam and Jaya, after learning about Anand's true mission, informed him that Babu was his long-lost brother. This created a profound personal conflict for Anand between his police duties and family loyalty.

Foreshadowing: The earlier moment when Anand agreed to impersonate Babu set the stage for this family revelation.

  • Anand
  • Babu
  • brother
  • twin
  • revelation
  • family
Q6

Why did Babu escape from prison to kill Anand?

When Babu learned that Anand was impersonating him and infiltrating the gang, he interpreted this as a betrayal and a threat to his criminal identity. Enraged and still suffering from his psychological condition, Babu escaped from prison with the intent to kill Anand for what he perceived as treachery.

Foreshadowing: The impersonation plan inherently created this dangerous confrontation once Babu discovered it.

  • Babu
  • prison escape
  • Anand
  • attack
  • revenge
Q7

How did Mangalam reveal her identity to Babu?

When Babu cornered Anand after escaping prison, Mangalam intervened and directly revealed that she was his mother. This emotional confrontation, combined with the mention of his father Ramnadhan who Nagappan had murdered, finally broke through Babu's psychological barriers and restored his true identity.

Foreshadowing: Babu's earlier attraction to Mangalam's house planted the seeds for this maternal recognition.

  • Mangalam
  • mother
  • revelation
  • identity
  • memory return
Q8

Why did Babu agree to team up with Anand against Nagappan?

After learning from Mangalam that Nagappan was the one who killed his father Ramnadhan, Babu's entire perspective shifted. Realizing he had been raised by his father's killer as a weapon against everything his family stood for, Babu united with Anand to bring Nagappan to justice and reclaim his true identity as Sekhar.

Foreshadowing: The father's murder was established at the very beginning of the story, waiting to be connected to Babu's reality.

  • Babu
  • Anand
  • Nagappan
  • father
  • revenge
  • alliance
Q9

How did Asha react when she discovered Anand was impersonating Babu?

Asha, Babu's girlfriend, initially discovered Anand's deception but he immediately surrendered to her and explained Babu's medical condition, the amnesia and madness that resulted from his injuries. Understanding the circumstances, Asha forgave Anand and teamed up with him to help defeat Nagappan and his gang.

Foreshadowing: Asha's relationship with Babu positioned her to learn the truth during the impersonation.

  • Asha
  • Anand
  • impersonation
  • forgiveness
  • alliance
Q10

Why did Mangalam and Jaya become heartbroken when they saw Anand with money?

When Mangalam and Jaya saw Anand with a briefcase full of money, they believed he had become corrupted, either succumbing to the criminal lifestyle or betraying the police mission for personal gain. Their heartbreak stemmed from feeling betrayed by someone they trusted, until the full truth about his undercover assignment was revealed.

Foreshadowing: The briefcase represented the dangerous overlap between Anand's criminal persona and his true mission.

  • Anand
  • Mangalam
  • Jaya
  • money
  • misunderstanding
  • reconciliation
Q11

How was Babu unaware that Nagappan killed his father?

Nagappan kidnapped Sekhar when he was just a child and raised him as his own protégé, never revealing the truth about killing Ramnadhan. Babu grew up believing Nagappan was his mentor, completely blind to the fact that the same man had murdered his father and torn his family apart.

Foreshadowing: The initial murder scene established Nagappan as the killer, but Babu was whisked away before he could ever learn this.

  • Babu
  • Nagappan
  • father
  • killer
  • identity
  • secret
Q12

Why did Anand end up as a club dancer?

After the family fled to Madras following their father's murder, Anand's path took him to become a club dancer. While the summary doesn't detail the exact circumstances, this profession placed him in the same urban landscape where his brother Babu operated as a criminal, ultimately leading to their parallel fates intersecting.

Foreshadowing: The family's departure to Madras created the separate life paths for both twins.

  • Anand
  • club dancer
  • profession
  • Madras
