The story revolves around a young girl named Ishi, whose father, Mayank Kumar, is murdered in a hospital. The CID team, led by Inspector Daya, investigates the case and discovers that Mayank was being threatened by someone and had been staying in a hotel with his daughter to protect her. The team finds a letter in the girl's pocket, pleading to save her as her life is in danger.
As the investigation unfolds, the team learns that Mayank had a son named Rohan, who was kidnapped by his loyal servant Ramu Kaka many years ago. However, it is revealed that Mayank had handed over Rohan to Ramu Kaka due to some danger and did not want his son to grow up in the shadow of death.
The CID team eventually discovers that Rohan is the one who murdered his father, Mayank, and had also kidnapped his own sister, Ishi. The team apprehends Rohan, and in the end, it is revealed that the mastermind behind the murder was a man who had been seeking revenge against Mayank for allegedly killing his son.
