Niranjan, son of Sir Rajendra falls in love with a poor Pujari's daughter Sharada. This is resented by his father and Niranjan and Sharada leave the town. In the Train they meet dada Gyan and his daughter Prabha. Gyan Dada helps them and gets them married too. When Niranjan gets a job in another town, he starts by train. Unfortunately, the trains meets with an accident. Niranjan becomes mad due to the shock caused by the accident and he starts wandering in jungles.
Here Sharada gives birth to Baby Madhuri. She does tailoring jobs for survival. After a few years, Madhuri joins the same school where Prabha is teaching. Dada Gyan is dead by then.
Coincidentally mad Niranjan comes to this town and meets Madhuri.They become friends. Sir Rajendra and Prakash-his younger son are the trustees of the school where Prabha is teaching.
On one visit Rajendra gets attracted towards Madhuri and plays with her, while Prakash promptly falls in love with Prabha.
After a few days, Prakash refuses to marry Prabha fearing his father's ire and Prabha decides to commit suicide. Madhuri learns this and she brings Sir Rajendra there. He has already regretted losing one son so Rajendra stops Sharada from suicide and blesses Prakash and her.
Niranjan appears there and when he tries to sit on Rajendra's car. Prakash beats him, thinking him to be a mad man. Due to this impact Niranjan regains his memory and remembers everything.
Now everybody recognises everybody and all is well with Niranjan/Sharada and Praksah/Prabha.
