A young boy becomes a target for crooks, after he claims to remember his past life and mentions precious jewels in a golden fortress.

Set in the holy city of Benares, this is the second film about the detective Feluda, in which he goes for a holiday along with his cousin, Topshe and his friend, Lalmohan Ganguly. But the theft of a priceless deity of Lord Ganesh (the Elephant God) from a local household forces him to investigate.

Lalmohan Ganguly, alias Jatayu − a sidekick of Feluda − gets invited to Mumbai (previously Bombay) to watch the shooting of a film based on a novel written by him. Once in Mumbai, he, along with Feluda and Topshe gets embroiled with underworld kingpins. He seems to have transported the Nana Sahib's necklace. But fortunately because of Feluda the real thief is caught and convicted. Although the original story was written in the 1970s, the movie is set in more recent times and depict the real problem of underworld involvement in Bollywood.

Detective Feluda, with the help of his nephew Topshe and the writer Jatayu, investigates smuggling and illegal trading in ancient sculptures across India.

Feluda, the famous Bengali detective tackles an international buyer, a corrupt arts agent, numerous henchmen and impostors in this story that revolves around a painting of Jesus by the famous Italian painter Tintoretto.

By accident, more than anything else, the three find themselves beside the grave of Thomas Godwin. The grave was dug up by some miscreants for unknown reasons. The rather colorful history of Mr. Godwin makes Feluda curious to know more about the man.From the diary of Thomas' daughter Charlotte, Feluda finds that a very precious clock went to Thomas' grave with him. To his surprise, Feluda finds that another party knows about this clock and they are trying to get it aided by the letter with them. Thanks to the brilliance of the detective and the help of 'Haripodobabu', the chauffeur of Mr. Ganguli, a new introduction in this book, their plot is foiled.

Feluda alias Pradosh Mitra, a private detective is invited by a rich former Zamindar (and a retired big game hunter) in North Bengal. The task is to solve a riddle which was written by an ancestor long time ago. The riddle ostensibly contains clue to finding hidden treasure that belongs to the family of the Zamindar. When Tarit Sengupta, the personal secretary of the Zamindar is killed in mysterious circumstances, Feluda finds out that Tarit had already solved the riddle, and was in the process of stealing the treasure when he was killed. Then the mystery thickens as there are many suspects. At the end the man-eating Tiger appears to give the story a new dimension. How does Feluda Solve it? See it to believe. The mastery of Satyajit Rays's writing and direction of Sandip Ray can be seen here.

Feluda and his cousin Topshe goes to Lucknow with Topshe's father to spend the Puja vacation. They arrived at the house of Dhirendra Kumar Sanyal, a friend of Topshe's father. That evening Dr. Shrivastav also came to Dhirendra Kumar Sanyal and tells him about last night, a thief tried to steal his 'Ring of Aurangzeb' (The Emperor's Ring) which was given to him by Pyarilaal Seth. After the incident Dr. Shrivastav has been afraid and asks Dhirendra Kumar Sanyal to keep the ring safe. Dhirendra Kumar Sanyal agreed and keeps the ring to his home. But someday the ring goes missing from there. Then Feluda and Topshe started investigation for the culprit. Meanwhile, Feluda meets an interesting person in doctor's neighborhood, Mr. Bonobihari Sarkar. Bonobihari babu has ferocious and poisonous creatures like crocodile, African tiger, hyena, rattlesnake, scorpion and black widow spider in his own home.

The movie consists of two Feluda stories by Satyajit Ray, Samaddar-er-Chabi and Golokdham Rahashya, shown on either half of the film. It was a tribute to the 50-year anniversary of Feluda and a sequel to Royal Bengal Rahashya (2011).

The suave Prodosh C. Mitter aka Feluda has ruled over our hearts with his sharp wit, impressive intellect and astute observation skills for over five decades now! The story starts off with the murder of Birupaksha Majumdar by Vishnudas Balaporia in the cold Darjeeling Mountains. Feluda, Topshey and Lalmohun Ganguly investigate.

Pradosh C. Mitter AKA Feluda, Topshe, and Lalmohan Ganguly go to Puri for vacation. One evening, the trio spot odd footprints on the sand. Later, Lalmohan goes to meet Lakshman, an astrologer who is presumably gifted with extrasensory perception. Soon they stumble upon Roopchand's dead body lying on the beach. Feluda figures out the mystery and gathers everyone at Bhujanga Niwas and tells everyone that Bilas Majumdar is actually Animesh Kumar Sarkar, a smuggler by profession. Feluda tells them that the actual Bilas Majumdar had died three weeks ago in a hospital in Nepal. Why?

In this case, Feluda, Topshe and Jatayu go to Srinagar and Kashmir where they come across a spine chilling mystery. They meet a retired judge, Siddheshwar Mallick, and his group who have also come for a holiday. They travel together to Gulmarg, Khilanmarg and Pahalgam. The judge has given death sentence to many convicts in a career spanning three decades and wants to find out whether he had made a mistake in doing so by calling the spirits of those convicts by planchette. The judge suffers from angina due to which he had to voluntarily retire at the age of 65 and he has a son, who is addicted to gambling. He finds out that he had misjudged two of his cases, one of a Bihari and another of a Kashmiri. In the meanwhile, there are life attempts on the judge's son Vijay and on Feluda twice. Soon after, during Pahalgam visit, the judge gets murdered and a precious diamond ring worn on his right hand gets stolen.
