An air of melancholy surrounds Suryadev's wife, Devi Sandhya, who is despondent as she is unable to bear the heat that flows through her husband's body. She steals a magic potion that can replicate objects from its own shadows and uses it to create a clone of herself, Chaya. While the unceasing war between the Asuras and the Devas continue, Shiva decides to summon the Lord of justice to bring order. Shiva instructs the child to be born into Suryadev's home and thus Chaya gives birth to Shani!

Suryadev is furious on seeing his son and questions Chaya's character, as he firmly believes that the baby is not his. Meanwhile, an eclipse is cast over the blazing sun, which surprises all the Gods and makes Suryadev cry out in agony. Suryadev curses the newborn to die the moment a ray of sunlight falls on him. Chaya sets off with the baby on a horse to a forest, where the rays can't reach him. She prays to Lord Shiva to help her name her son and he christens him as, 'Shani'.

Suryadev asks Indira and Vishwakarma to stop fighting as Shiva has summoned a force that will be the keeper of justice. Meanwhile, Chaya returns to Suryadev's fortress and tries to convince him to spare Shani from his curse, but a furious Suryadev commands her to keep Shani away from him. 10 years pass by, when two men arrive at the forest and try to fell a tree. They are shocked to see Shani, who warns them of grave consequences if they cut it down without a proper reason.

A simple flick with a twig from an angry young Shani breaks the leg of one of the two men who arrive to fell the tree in the forest. However, Shani burns his hand when he is exposed to the sunlight while trying to save the other man from falling off a cliff. Meanwhile, when a concerned Chaya reaches out to Shani, he is pensive and questions her about why sunlight has a negative effect on him. Will Chaya reveal the truth to her outcast son?

Chaya tells Shani that all his questions will be answered with time and gives him a stone that could help him drive away his loneliness. Meanwhile, when a hungry demon sent over by Vishwakarma tries to eat a crow, Shani responds to the crow's cry for help and warns the demon to stay away from him. A fierce duel follows between Shani and the demon as the former tries to stop the demon from wrecking havoc. Will Shani defeat the evil?

Shani ends the battle with the demon by defeating him at the break of dawn. Meanwhile, the crow saves Shani from being hit by the ray of sunlight. Later, Chaya questions Shani about his actions. But, the Shani's reply and determination towards justice leaves her speechless.

After Kakor's endless efforts, Shani finally accepts him as his 'Vahan'. Earlier, Yama and Indradev figure out that Suryadev is hiding someone. Later, Guru Shukracharya comes to investigate his henchman's death and finds out about Shani.

Curious over Chaya's actions, Yama and Yami follow her into the jungle. Will they find out about Shani? Elsewhere, Guru Shukracharya sends his demons to look for Shani, who he considers to be a very powerful being.

Shani finally comes face to face with the demon lurking in the forest. Without a second thought, he declines the demon's request of following him to meet Guru Shukracharya. Earlier, Yama and Yami get closer to discovering Chaya's secret.

After defeating Guru Shukracharya's demon, Shani eagerly waits for Chaya. Running out of patience, Shani goes to visit her, but gets shocked to find her missing. He confronts Kakor for Chaya's whereabouts, who takes him to Suryalok. On seeing Chaya, singing the same lullaby for Yama and Yami, which she used to sing for him, Shani is left heartbroken. Earlier, on finding Yami sick and wounded, Suryadev compels Chaya to stay with her and not go to Shani. What will Chaya do now?
