[1] It gets its title from Puri, a city located on the shores of the Bay of Bengal which is a popular tourist attraction in East India.

[2] Disturbed by the heat and humidity of Calcutta in June, (combined with frequent electricity failures) the "Three Musketeers", Pradosh C. Mitter (Feluda), Topshe, and Lalmohan Ganguly (Jatayu) go to Puri for vacation.

There they stay in Neelachal Hotel, owned by Lalmohan Babu's landlord's classmate, Shyamlal Barik.

After conversing with Mahapatra regarding the victim Singh—who had come to Puri from Nepal and had been shot dead, but the weapon hasn't been found—the "Three Musketeers" then go to Sagarika and meet Nisith Bose, D.G.

Nisith reveals his employer's full name: Durga Gati Sen who is currently suffering from gout.

They meet Mr. Sen in the terrace of his house, who shows them many manuscripts, of which the most famous and the oldest ones are the Ashtadashasahasrika Pragya Paramita and Kalpasutra.

While roaming on the beach, the trio meet a man named Bilas Majumdar, who introduces himself as a famous wildlife photographer.

Next morning the trio go to the Puri railway station to buy a newspaper where they meet Nisith Bose.

When Mahim leaves, Feluda tells Topshe that Nisith took all his bedding with him but left his wallet in his room.

In the night, after a thrilling climax, Feluda catches the culprits: Bilas Majumdar and Laxman Bhattacharya.

Feluda gathers everyone in Bhujanga Niwas and tells everyone that Bilas Majumdar is actually Mr. A. Sarkar, a smuggler by profession.

Feluda tells them that the actual Bilas Majumdar had died three weeks ago in a hospital in Nepal.

Feluda returns the Pragya Paramita to Mr. Sen and tells him that he retrieved it from the Nulias who found it from the sea.

Next morning, the trio go to Sagarika, where Feluda tells Mr. Sen that he was the one who was roaming in the beach with his walking stick and was leaving those odd footprints.

The film is directed by Sandip Ray and stars Indraneil Sengupta as Feluda alongside Ayush Roy and Avijit Guha as Topshe and Jatayu respectively.
