In denial of her son’s death, Sunder’s mother keeps doing various acts in madness. She keeps serving food for Sunder, talks with his photos, and keeps feeling that her son has returned. Meanwhile, Shankar and Sheila fall in love. But in her madness, Sunder’s mother starts preparations of Sunder’s wedding with Sheila. Sunder’s face-burnt body is found and the mystery continues whether his death was an accident or a murder.
