Diya Aur Baati Hum's September 18th episode: Sandhya comes to know that Chote Raja has fallen severely ill due to his repeated visits to the forbidden part of the jungle. The report says that he was exposed to radioactive radiation. She visits the jungle to discover the mysteries.
The jungle seems apparently calm with its amazing natural scenery; nothing suspicious is there. Sandhya lights a fire with dry leaves and woods to see whether it attracts anybody! She hears the loud rings of a fire alarm.
A group of men with specials suits and masks comes out with fire extinguishers. Sandhya hides herself and watches them. She abducts a man and takes his suit to guise herself. She joins the group of men to see the secret area they have come from.
Sandhya is shocked to find that the men open a door which is covered by trees and a water jet. She understands that they have designed the place so cleverly that no outsider will find its existence!
Sandhya enters the factory and discovers the power plant where the Garjana team has developed a devastating atom bomb to shake the country on 2nd October. She is trembled by horror to imagine the intensity of the destruction. She thinks she has to ruin this plan anyhow. Sajni informs Shekhar and Bade Raja that Sandhya is missing in the village. A Garjana commando informs Shekhar that Manjari is able to speak now!
The Rathi family members arrange Ganesh Puja in the house. The neighbors come to remind them that Sooraj will be taken to the asylum if his test reports say that he is mentally unstable.
Lalima takes Sooraj to a place where she has arranged a set up to cure Sooraj. She talks with a man who assures that everything is ready as per her instruction—she will be surrounded by fire with full protection. Sooraj will try to rescue her and thus he will be able to overcome his phobia.
