Kajal, a beautiful young lady, falls in love with Ravi, a rich and handsome man. They happily marry with the blessings of Ravi's mother, Lakshmi Devi. Ravi's greedy uncle Dhirendra and cousin Narendra are disappointed to hear of this, because they are next in line to inherit the family's vast wealth after Ravi. Dhirendra hires hoodlums to murder Ravi. The hoodlums, along with Narendra, try to murder Ravi. During the struggle, Ravi manages to kill his cousin Narendra and both of them topple over a cliff. The hoodlums flee. The news reaches Ravi's family. Widowed and depressed, Kajal moves to another city along with Ravi's mother Lakshmi Devi.
Raja, a handsome, rich and good-hearted guy riding a motorcycle, accidentally knocks down Lakshmi Devi on the street, takes her to her home, and thus meets Kajal. He falls in love with Kajal, and tries to express it, but she cuts him short and reveals that she was already married and now a widow. Taken aback briefly, Raja returns with his suit, but Kajal continues to resist his advances. Raja's rich father, Ramakant, dislikes the idea of his son marrying a widow and tries to get rid of Kajal. After this, Raja quarrels with his father and begs Lakshmi Devi for her permission to marry her widowed daughter-in-law. Lakshmi Devi persuades Kajal to marry Raja, saying that Kajal has a long life ahead of her, she has no child, and will be totally alone after Lakshmi Devi's death. Kajal finally accepts at her mother-in-law's behest. Lakshmi Devi conveys the acceptance to Raja, but she also tells him how reluctant Kajal was, and advises him that even after the wedding, he should go slow and not approach Kajal in a sexual way until she genuinely, in a heartfelt way, accepts him as her husband.
News of Raja's forthcoming engagement is the last straw for his father, who throws him out. Raja now has to look for a job. His friends open a garage with him. He meets with an accident and is hospitalised. Kajal rushes to see and realises that she is also in love with him. They admit their feelings for each other.
A man is attacked by a gang of ruffians waiting to rob him, and Raja saves him. They soon become good friends. Little does Raja know that this man is none other than Kajal's first husband and Lakshmi Devi's much-mourned son, Ravi.
When Raja introduces Ravi to Kajal, she is shocked to learn that Ravi survived Dhirendra's attempt to murder him. However, she stays with Raja. Dhirendra learns about Ravi. He kidnaps Kajal and Raja, demanding Ravi's property in exchange. Raja escapes and beats Dhirendra along with Ravi. They find Kajal tied up with a bomb strapped around her. Ravi manages to stop the bomb timer. Dhirendra returns to kill Raja. Enraged, Ravi pushes him and sets the bomb off, causing a large explosion that kills both. Raja and Kajal honor Ravi for his sacrifice.
