A group of friends plan a picnic, but one of them, Mayank, doesn't show up. His son, Ishi, is found with a letter saying "Save my girl, for God's sake. Her life is in danger." The group, led by Inspector Daya, starts investigating and discovers that Mayank was a businessman from Pune who had escaped to Mumbai with his son to save him from danger.
As they dig deeper, they find out that Mayank's first wife, Mamta, had left him and gone to Canada, and that Mayank had a trusted servant named Ramu who had taken care of his son, Rohan (also known as Manu). However, Ramu reveals that Rohan is not Mayank's biological son, but rather the son of a man who had been seeking revenge against Mayank.
The revenge-seeker, whose son had been killed by Mayank, had paid Ramu to make Rohan hate Mayank, and eventually, Rohan killed Mayank. The revenge-seeker then kidnapped Ishi, but was caught by the police. In a surprising twist, it is revealed that Rohan is actually the revenge-seeker's biological son, and that Mayank had raised him as his own.
In the end, Ishi is reunited with his family, and the revenge-seeker is punished for his crimes. The episode ends with Ishi enjoying ice cream with his friends and family.
