The city lights were on all night, but some streets were dark. One night there, a young woman named Sumi goes missing. His disappearance disturbs the peaceful atmosphere of the city. Journalist Rahul, Sumi's friend, sets out to find her.

Thousands of questions were running through Rahul's mind. Why did Sumi suddenly disappear? Was she really hiding something? He starts talking to Sumi's family and friends. “Sumi is such a good girl, she would never do this,” said Sumi's mother, Runa, with tears in her eyes.

Sumi's friend Akash also said, “She was talking about some changes recently. He was worried about some things.” Hearing this, Rahul could understand that there are some secrets in Sumi's life.

Now Rahul goes to Sumi's last seen place. A little away from the city center is an old cafe, where Sumi used to visit sometimes. The owner of the cafe, Amal, said that Sumi had brought some people one night, then suddenly left.

The question arose in Rahul's mind - who was he? Amal said, “They were saying something unusual. Sumi was very excited with them.”

Rahul got out of there and entered the dark alleys of the city. Saw some young men there. Listening to them, it seems that they know about Sumir. A young man, seeing Rahul, said, "If you come for Sumi, listen to us."

The young man's name was Titu. He said, Sumi was looking for some information. They came to know about a secret organization. The organization is linked to the underworld of the city.

An apprehension arose in Rahul's mind. He could sense that Sumi was up to something serious. Titu took him outside the city. There was an old dilapidated building. “This is where Sumi went,” said Titu.

Entering the building, Rahul found some old papers and files. They contained confidential information and some of Sumi's documents. Sumi went to investigate some unusual activity happening in the city.

After reading this much another thought came to Rahul's mind. Did Sumi put herself in danger and go after this information? Rahul was realizing that it would be more difficult to find him.

Rahul went deeper. Suddenly, he heard a strange noise. He went down. Went down and saw Sumi lying unconscious in a room. Rahul's heart started pounding. He quickly went to Sumi's side and tried to wake her up.

“Sumi! Sumi! How are you?” Sumi slowly opened her eyes. He looked and saw Rahul. "Rahul! Rescue me!” she said

Rahul consoled her, “Everything will be fine. You are safe.” But Sumi had a look of fear and despair on her face.

By now Rahul should have understood, explaining somewhat the mystery behind Sumi's predicament. Sumi informs that she is involved with a big evil gang, who wants to destroy the peace of the city.

“They wanted to catch me because I got to know some secret information,” said Sumi.

Rahul came out of the city with Sumi safely. "If we reveal these facts, we can break their power," Sumi added.

Rahul also expressed the same opinion. They decided to give the information they gathered to the city police.

With the help of the police, they were able to take effective action against the vicious gang. The people of the city knew, due to this bravery of Sumi and Rahul, the city regained peace.

Finally, Rahul and Sumi vow, they will never back down. In the darkness of the city, they will shine a light of hope and courage.

Thus ended their night's expedition, but the story of the city would live on.
