Joi Baba Felunath () is a 1979 Indian Bengali-language mystery film directed and written by Satyajit Ray. Featuring an ensemble cast of Soumitra Chatterjee, Santosh Dutta, Siddartha Chatterjee, Utpal Dutt amongst others, it is an adaption of the eponymous Feluda novel and serves as the sequel of Sonar Kella. Shortly after the demise of actor Santosh Dutta who portrayed Jatayu's role, Ray remarked that it was impossible to ever make a Feluda film again without Dutta. Plot Pradosh C. Mitter (a.k.a. Feluda), his cousin Tapesh (a.k.a. Topshe) and the thriller writer Lalmohan Ganguly (a.k.a. Jatayu) go to Varanasi during the Durga Puja for vacation. There they meet a Bengali family, the Ghosals. Upon hearing that Feluda is a private investigator, the Ghosal family patriarch entrusts him with the task of finding out the thief of the attempted theft that took place in their house. Meanwhile, the arrival of a saint by the name of 'Machhli Baba' in Varanasi rouses the excitement of the local people. A very valuable property of the Ghosals, a golden Ganesh statue, about three inches in height, was the target of the thief. On the other hand, Maganlal Meghraj, a wealthy Marwari businessman, had his eyes on the Ganesh for a very long time. He learns about Feluda's involvement in this case. He invites the trio to his house and tries to bribe Feluda with Rs.2,000 in order to stop the investigation. Feluda refuses to do so, which angers Maganlal, and he sets up a knife throwing show, using Jatayu as bait (much to the viewer's amusement). After the incidents in Maganlal's house, Feluda takes a vow - either he'll avenge Jatayu's harassment, or he'll quit his job of being a detective. Although warned by Maganlal, Feluda didn't lose interest in the case, and deduces that Machhli Baba is actually a fraud working for Maganlal. A member of the Ghosal family, Bikash Singha, was also bribed by Maganlal to steal the Ganesh and hand it over to him. Feluda gets hold of Bikash and makes him confess his involvement in the theft. But Bikash states that when he went to steal the Ganesh, it was not there. Several questions arise in Feluda's mind. Where is the Ganesh, then? Why was the innocent idol-maker of the Ghosals, Shashibhushan Pal, murdered brutally? What plan did the Ghosal family head hatch upon with his grandson to save the Ganesh?
