At the heart of the story is Rumi Sharma (22), a young playwright and final-year mechanical engineering student grappling with the profound loss of his father. His relationship with his mother is strained, adding to his emotional longing, and widening the void he has carried in his heart since childhood. Rumi's life is held by two pillars: Vikas, his childhood friend, a jovial and jaunty boy of the mountains, and Saanjh, his elder sister whose nurturing and caring presence serves as both an emotional anchor and a unifying force of the family.

During the college fresher event, Rumi experiences a magical moment, a moment that feels beyond himself and alters the course of his life. Across the crowded auditorium, his eyes catch a glimpse of Naziya Hassan, a figure shrouded in mystery and allure. Rumi follows and finds what he was unconsciously seeking.

Naziya Hassan (19) is a CS/IT engineering fresher, a solitary figure. Her past is veiled in tragedy, which changed her forever. She was once filled with stories, liveliness, and poetry. Adil, her younger brother, is the only radiance she has in her world. Despite the shadows that linger around her, Rumi's encounter with Naaz stirs a soulful emotion within him, an emotion so deep that it defies articulation. In each other's presence, they dream and together they paint a world of boundless possibilities. Long walks, sunsets. They start spending time together, eventually healing each other, and slowly their past becomes a memory.
But, an unexpected turn in life tears them apart, setting them on a long voyage of pain and detachment. Their world remains unfinished.

The narrative shifts to Delhi, a bustling metropolis pulsating with power, fury, and unyielding concrete. As Rumi grapples with a multitude of emotions, he finds himself torn between two worlds: one where Naaz is, and the other where Rumi struggles in solitude.

In a new city, Rumi’s only hope and connection to reality is theatre, soon becoming a prominent playwright of Delhi. Rumi's metamorphosis leaves Vikas, Saanjh, and those around him in a perpetual state of unease and frustration. Their brother, the light of their life, is now a lost soul.

Rumi’s heart is eager to meet Naaz. The agony of separation from his lover devours Rumi's essence, leaving a void behind. Forced to flee Shimla by one incident, destiny brings him back. Upon his return to Shimla, Rumi confronts himself with reality, and a flood of memories and stories rushes back. Rumi glimpses a ray of hope; he knows that to reunite with Naaz, he must transcend barriers and mend past wounds.
Will they be able to meet in this world? Or does something await them in the greater beyond?

"Ruminaaz," the film, is a tale that delves into the depths of hope, resilience, love, and grief — the very essence of our humanity. The film will eventually leave the audience with silence to ponder upon, a sense of completeness, and satisfaction.
