Obeying his widow's mother's wishes Punjab-based Dharam Singh gets himself engaged to Nimmo, and re-locates to London. He gets employed but circumstances compel him to get married to Kamal, who passes away shortly after birth to Dolly. Unable to return, he brings up Dolly on his own. Years later Dolly has grown up, is insolent and determined to live life her own way, leaving Dharam alone to deal with facing his ailing and debt-ridden mother and an unwed Nimmo.
