Fireflies: Parth aur Jugnu

All hell breaks loose when Parth, a class 9 student who struggles with exam phobia, fails his exams. Everyone around him is concerned about how his academic failure has dented his father’s reputation.

Jugnu, a boy with super-human powers, creates havoc in Parth’s school. Parth increasingly starts fearing Jugnu's presence but decides to return to the jungle and face his fears.

Parth's friend, Johnson, decides to steal money from his dad to pay the re-evaluation fee for his papers and encourages Parth to do the same. As Parth struggles to make a decision, nani senses his dilemma.

Strange events occur at the CRC as several recovered patients have a relapse. Arjun is convinced that Vinita hiding something from him. At night, Parth sneaks into the woods to find Jugnu.

Parth confronts Jugnu, who is forced to reveal his story and how his destiny is tied to the Sanjeevani tree. Parth realises that Jugnu is not the monster everyone makes him out to be.

Parth introduces Jugnu to his friends, all of whom agree to take Jugnu to school. The kids seem to have a good time until Hooda enters the classroom.

Nani believes it is no longer safe for her to keep Ohri's book with her. Sleeman decides to change his strategy after another failed experiment. Arjun focuses on conducting the tests outside the CRC.

Sleeman ultimately decides to track down Jugnu as he is the key to accessing Sanjeevani. Laffu unintentionally talks about nani's copy of Ohri's book to Nyasa.

Sleeman blackmails the mayor into ordering a lockdown at the CRC and in the jungle. An anxious Anamika asks the kids to stay indoors. When Parth and the group learn about the lockdown, they decide to sneak into the jungle.

The fateful night of Amrit Poornima is here, and it is Sleeman's only chance to get his hands on Sanjeevani and become immortal. His is a race against time, but so is Jugnu's. Who will win?
