What Happens in Daag: Full Plot Summary

The whole story of Daag (1973) 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.

Sunil Kohli [Rajesh Khanna], a young man, falls in love with and marries Sonia Kohli [Sharmila Tagore]. During their honeymoon, rough weather forces the couple to seek shelter for the night in a bungalow owned by Sunil's employer. While Sonia is alone, Dheeraj Kapoor [Prem Chopra], the employer’s son, makes a bold attempt to assault her. Sunil arrives just in time to intervene, and in the struggle that follows, Dheeraj is killed. Sunil is arrested and sentenced to a life term in prison.

While being transported to prison, the police van is involved in an accident, and all occupants are presumed dead. Years pass, and Sonia, now a schoolteacher, raises their son on her own. She eventually discovers that Sunil is alive, living under a new identity as Sudhir. He is now married to a wealthy woman named Chandni [Rakhee Gulzar].

Following the accident, Sunil had met Chandni, who had been abandoned by her lover after becoming pregnant. In exchange for help in starting a new life, Sunil agrees to marry Chandni to provide legitimacy to her unborn child. As the law closes in once again, Sunil must answer not only for his past but also for the charge of bigamy.

Daag Plot Explained: Your Questions Answered

The questions people ask most about Daag (1973): 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 does Sunil kill Dheeraj during the honeymoon?

Sunil kills Dheeraj in self-defense after discovering him attempting to assault Sonia. When Sunil arrives at the bungalow, he finds Dheeraj attacking his wife, and during the ensuing struggle to protect Sonia, Dheeraj is fatally wounded. The killing, while accidental in the heat of the moment, leads to Sunil's arrest and life sentence.

Foreshadowing: The couple's decision to seek shelter at the employer's bungalow, though driven by bad weather, places Sonia in isolation and vulnerable to danger.

  • self-defense
  • assault
  • Dheeraj Kapoor
  • murder charge
  • honeymoon
Q2

How does Sunil survive the prison van accident?

The police van crashes while transporting Sunil to prison, and in the chaos, all occupants are presumed dead. Sunil manages to survive the accident, though the specific details of his survival are not detailed in the summary. This presumed death allows him to escape his previous identity and start life anew under the name Sudhir.

Foreshadowing: The van crash occurs shortly after Sunil's conviction, providing the opportunity for his identity to be officially erased.

  • prison van crash
  • presumed dead
  • escape
  • new identity
Q3

Why does Sunil agree to marry Chandni?

Sunil agrees to marry Chandni because she was abandoned by her lover after becoming pregnant and needed a husband to provide legitimacy to her unborn child. In exchange for Chandni's help in establishing a new life with financial support, Sunil agrees to the marriage so the child would have a recognized father and legal status.

Foreshadowing: After the van crash, Sunil finds himself without identity or means, making him vulnerable to arrangements that offer survival in exchange for significant personal sacrifice.

  • Chandni
  • marriage of convenience
  • legitimacy
  • unborn child
  • bigamy
Q4

Why does Sunil assume the name Sudhir?

After surviving the prison van crash, Sunil assumes the new identity of Sudhir to escape his past and start fresh. The crash officially killed his old identity, allowing him to become someone new. He uses this new identity to build a different life, eventually marrying Chandni and having a child with her.

Foreshadowing: The presumed death in the van crash provides the perfect cover for Sunil to abandon his original identity and avoid the legal consequences of his past actions.

  • new identity
  • alias
  • escape
  • Sudhir name change
Q5

How does Sonia learn that Sunil is still alive?

Years after raising her son as a single mother and believing Sunil died in the van crash, Sonia eventually discovers that Sunil survived the accident and is living under the new name Sudhir. The summary does not specify the exact method of discovery, but the revelation comes as a major turning point that reopens her hopes and forces difficult questions about their relationship.

Foreshadowing: The story's structure builds toward this revelation as a key moment that will determine the emotional resolution for both characters.

  • discovery
  • Sunil alive
  • Sudhir identity
  • reunion
Q6

What legal trouble does Sunil face at the end of the story?

At the end of the story, the law closes in on Sunil once again, forcing him to answer not only for his past crime of killing Dheeraj but also for the charge of bigamy. Since he married Chandni while still legally married to Sonia, he faces legal consequences for being married to two women simultaneously.

Foreshadowing: Sunil's decision to marry Chandni, though made with good intentions, creates a new legal problem that compounds his original situation.

  • bigamy charge
  • arrest
  • legal consequences
  • Chandni marriage
Q7

Why does Chandni need Sunil to marry her?

Chandni was a wealthy woman who was abandoned by her lover after becoming pregnant. Without a husband, her unborn child would be considered illegitimate in the social context of the time. By marrying Sunil (who had assumed the identity of Sudhir), she could provide her child with legal legitimacy and a recognized family name.

Foreshadowing: Chandni's vulnerability as an abandoned pregnant woman makes her willing to enter into a practical arrangement with a stranger who needs a new life.

  • abandoned pregnant woman
  • legitimacy
  • social stigma
  • Chandni background
Q8

What happens to Sunil and Sonia's relationship after the truth emerges?

The summary leaves the ultimate resolution of Sunil and Sonia's relationship uncertain. When Sonia discovers that Sunil survived and has built a new life with Chandni and a child, she faces the painful reality that her husband has another family. The story ends with Sunil confronting both his past crimes and the new bigamy charge, but the emotional outcome for the two original lovers remains ambiguous.

Foreshadowing: The narrative's dark and ambiguous tone, as noted in the meta notes, suggests the ending does not provide a clear romantic resolution.

  • Sonia
  • reunion
  • love triangle
  • emotional resolution
Q9

Why is Sunil sentenced to life in prison for killing Dheeraj?

Sunil receives a life sentence for killing Dheeraj Kapoor, even though the act occurred during what could be considered self-defense while protecting Sonia from assault. The courts likely viewed the killing as deliberate murder rather than justifiable self-defense, given that Dheeraj was overpowered during the struggle and died as a result of Sunil's actions.

Foreshadowing: The harsh sentence sets in motion the chain of events that follow, including the van crash and Sunil's assumed death.

  • life sentence
  • murder conviction
  • Dheeraj death
  • court judgment
Q10

How does Sonia cope after believing Sunil is dead?

After the van crash where Sunil is presumed dead, Sonia raises their son as a single mother and becomes a schoolteacher. She dedicates herself to her students while living quietly, keeping the past at bay. Her life represents resilience and sacrifice as she builds a new future without her husband, only to have that foundation shaken when she learns the truth about Sunil's survival.

Foreshadowing: Sonia's transition to teaching represents her attempt to create stability and purpose despite her loss.

  • single mother
  • schoolteacher
  • raising son
  • years passed
