In the heavens, Prithvi asks Vishnu to save the earth from Ravana's atrocities, upon which Vishnu promises to reincarnate on earth in human form to destroy evil. Meanwhile, on earth, King Dasharatha and Queen Kaikeyi return to their palace after a battle. In his chambers, Dasharatha recounts to his other queens, Kausalya and Sumitra, how Kaikeyi saved his life on the battlefield. For her valiance, Dasharatha has promised Kaikeyi two boons that she can ask from him at any time. However, Dasharatha has become sad that if he were to die, he has no heirs who could continue his Ikshvaku dynasty.

When their family priest, Vasishtha visits the palace, he advises Dasharatha to seek Sage Rishyasringa's blessings to beget a son. Rishyasringa arranges to perform yajna, during which a divine figure emerges from the fire, carrying a chalice of kheer. He advises Dasharatha to apportion the kheer amongst his three wives. The wives each take their share, with Kaushalya and Kaikeyi each serving a bite of their own to Sumitra.

At the naming ceremony, Vashishtha names Kaikeyi's son Bharata and Sumitra's twins Lakshmana and Shatrughna. Vashishtha prophesizes that all four sons will become paragons of ideal men. The deities from the heavens descend into Ayodhya in disguise to get darshan of Rama.

A couple years later, while Kaikeyi plays with a toddler Rama, Manthara tells her to dote on Bharat instead. Kaikeyi tells Manthara that neither of the three mothers discriminate between the four boys, so she should do the same.

While Rama is alone in his chamber, Kaagbhushandi appears in the form of a crow to get Rama's darshan. Upon seeing the toddler, he doubts that this mortal cannot be the powerful Vishnu, so he flies through the window and snatches the food from Rama's hand and flies away. Rama's hand extends into the skies and follows Kaagbhushandi as he flies. Kaagbhushandi realizes his mistake, he flies back into Rama's chamber and falls at Rama's feet. Rama appears before him in his divine form of Vishnu and blesses him that he will always be known as his ardent devotee.

The four boys are now teenagers and compete in a hockey game against each other, with Rama and Lakshmana on one team competing against Bharata and Shatrughna on the other. Rama purposely avoids making a goal because he doesn't want to make Bharata lose.

At Vashistha's hermitage, the brothers meet the head seeress, Arundhati, and find a mother figure in her. Arundhati sees that Rama does not eat because he is used to being fed his first morsel by his father. Out of compassion, she feeds him herself. At night, she also sings lullabies to all the boys at the hermitage.

The next morning, Vashishtha scolds Rama for violating the rules of the renunciant lifestyle. Rama bows down, regretting his behavior and promising to uphold the hermitage traditions going forward. Arundhati overhears their conversation and tells Vashishtha that along with the knowledge of scriptures and weaponry, princes must also be nourished emotionally in order to become compassionate kings. Vashishta agrees, so Arundhati teaches them music and other classes to instill positive emotions in the children, as well.

The princes return to the palace after completing their training. The queens choose the clothes and jewelry with which to adorn them. Manthara again tries instigating Kaikeyi against Rama, but Kaikeyi scolds her. When the princes arrive at the palace, Dasharatha and the queens are at loss of words in seeing their sons after many years. Vashishta praises the princes as great leaders and able rulers. During lunch, Manthara tries to serve Bharata a special sweet she made for him, but he refuses unless she feeds Rama first. The king and queens are delighted to see the unity amongst the brothers, but Manthara is annoyed.

In the palace, the queens admonish Dasharatha for sending the two young princes for such a dangerous endeavor, but Dasharatha reminds them that their Raghu clan must adhere to their duties by sticking to their words. Manthara is elated to hear that Rama has gone away, hoping that Bharat can again have a chance at the throne. She tries to feed Bharat his favorite sweets, but Bharat is upset by his brothers' departure and is uninterested in her cloying attempts to win his favor.

Meanwhile, on the way to Vishvamitra's hermitage, Rama and Lakshmana enter the territory of demoness Tadaka, who has been terrorizing the sages. Vishvamitra tells the princes how she has been cursed by sages to live as a demoness. Vishvamitra leads the princes into Tadaka's cave, where she awakens upon hearing the sound of Rama's arrow. Rama kills her with his arrow, and she appears in her original demigoddess form to thank Rama for liberating her from her cursed existence. Pleased with their courage and patience, Vishvamitra endows Rama and Lakshmana with heavenly weapons from the deities, gifting them with invincibility.

Once they reach Vishvamitra's hermitage, Rama and Lakshmana guard the surrounings while the sages perform their yajna. Tadaka's children, Maricha and Subahu (Ramayana) arrive to terrorize the sages. They laugh at the seemingly young and incompetent princes. However, Rama and Lakshmana slay them, protecting the sages and allowing the yajna to be completed. Later that day, a messenger from Mithila comes to the hermitage on behalf of King Janaka to invite Vishvamitra to the swayamvara ceremony of Janaka's eldest daughter, Sita. Vishvamitra accepts the invitation and tells the princes to accompany him.

In her palace, Sita prays to Shiva that she attains an ideal husband. Her cousin sister, Mandavi asks her what she would seek in a partner, and Sita says that she seeks someone in whom she sees Vishnu.

On the way to Mithila, Vishvamitra and the two princes come across Sage Gautama's hermitage, where his wife, Ahilya, has been turned into stone due to a curse. Rama liberates her with his divine touch. After transforming back from her stone form, she falls at his feet, and at her request, he sends her to heaven.

When Vishvamitra and the princes reach the palace, Janaka is drawn to their auras. Sita's friend passing by sees them, too, and runs to tell Sita of their magnificence. She wants to bring Sita to the guesthouse to see the princes herself, but Sita does not want to break tradition and promises to only marry the man who wins the swayamvara.

In the heavens, Shiva and Parvati rejoice over Rama and Sita's meeting. Parvati recalls that in her past life, Sita was Vedavati, who spent her life in prayer of Vishnu. The demon Ravana hears her chants and came to harass her. When he touches her, she curses him that in her next life, Vishnu will be her husband and he will destroy Ravana.

Back in the garden, Sita runs to the temple and prays to Parvati that Rama wins the swayamvara so she can marry him. From the heavens, Parvati grants her this wish.

Many of the suitors try to lift the bow together, but it does not budge. They get mad at Janaka for having such an impossible task. Janaka himself shares his disappointment with the incompetence of the men present. Upon hearing his disapproval, Lakshmana becomes angry, as he feels Janaka's statement is an insult to Rama's capabilities.

With Vishvamitra's blessing, Rama accepts the challenge to lift the divine bow. The suitors riducule him, wondering why this young man with a weak frame thinks he is capable. Meanwhile, Sita prays to Parvati that she will perform 14 years of penance in exchange for Rama lifting the bow and becoming her husband. In the heavens, Parvati and Shiva are agitated by her prayer, for now she has destined herself to 14 years of austerity if Rama is able to lift the bow. However, they both understand that this must be Vishnu's wish, and so Rama is able to easily lift the bow. While he strings the bow, Rama snaps it in half. Sita, her mother, and her friends are elated and Sita enters the chambers to garland Rama.

Rama reveals that he was the one who broke the arrow. Parashurama wonders what the true form of this divine person must be. He gives Rama his bow, that was once Vishnu's, and Rama not only strings the bow, but also appears before Parashurama in his Vishnu form. After Parashurama leaves contentedly, Vishvamitra suggests that Janaka send a messenger to Ayodhya so that Dasharatha can also be a part of the marriage ceremony.

That night, Vishvamitra gives his blessing for all four brothers to get married together, and Janaka happily agrees. The next day, Sita's younger sister Urmila overhears Lakshmana telling Rama that he will not marry, as he wants to devote his life to serving Rama. Urmila cries to Sita, and Sita comforts her, reminding her that if she and Lakshmana are meant to be, then the gods will definitely bring them together.

The next day, demon king Banasura, upset that he didn't win the swayamvara, sends a letter to Janaka threatening him to marry Sita to one of the demon kings or else she will be abducted. Janaka sends his brother Kushadhwaja to attack the demon's kingdom. He tells the queen, and they both become worried for Sita.

Lakshmana shoots the arrow at Sita, and Rama and Urmila rush to the scene. Rama realizes that the person in front of them is not actually Sita, but Banasura who has taken an illusory form. As Lakshmana slays the demon, the real Sita appears from the garden.

The next morning, Shatananda, the family priest, warns King Janaka that Ram and Sita cannot get married because their birth charts do not align. As they process this news, Dasharatha and his family arrive in Mithila. Janaka welcomes them while Sunaina tells Sita this wedding cannot happen. Sita tells her mother that she would rather give her life than to forsake marrying Rama. At night, Vishvamitra and Vasishtha advise that the couple get married during an auspicious time frame the next morning, which would ensure a successful marriage.

In the heavens, Indra tells Shiva and Parvati that Rama and Sita's happy life will prove disastrous for mankind. Earth is in need of Rama to destroy the evil of the world, and for that, he will need to leave Ayodhya. The deities plan that Chandra will appear at the wedding as a nymph and distract the families so the marriage ceremony is not completed within the auspicious timeframe.
