Kyon Ki…

Anand Rai Singhania is brought in by court order and undergoes an initial evaluation by the sanatorium's doctors. He does not display obvious insanity at first, but a violent reaction when a housefly lands on the table convinces the doctors to admit him. This admission marks the beginning of his controlled confinement within the facility.

Anand begins to cause a commotion almost every day, behaving childish and resisting the hospital routine. Tanvi Khurana grows weary of his antics and demands that Anand be thrown out of the asylum. Sunil, a fellow doctor, tries to navigate the fragile dynamic between them.

Sunil finds Anand's diary and hands it to Tanvi, sparking revelations about Anand's hidden past. The diary shifts the perception of Anand from a mere troublemaker to a patient with deep-seated trauma. It becomes a catalyst for rethinking his treatment.

Tanvi reads the diary and learns about Anand's sorrowful history, including the loss that haunts him. She confronts her own earlier harshness toward him and feels remorse. This reflection begins to thaw their strained interaction.

The diary reveals Anand's college love for Maya, a vivacious nun in Romania. Maya's responses are complex, and his hopes for a future with her are fueled by longing and emotional turmoil. The backstory sets up the tragedy that follows.

Anand threatens to set fire on himself on the rooftop of a church to elicit a reaction from Maya. In the ensuing moment, Maya steps in and unexpectedly confesses her love for him. That revelation becomes a pivotal shift in Anand's sense of possibility.

Maya teases Anand with a series of pranks, including pretending she can't swim. In a cruel game, Anand eventually leaves her in a swimming pool, not believing her truth about swimming ability. Maya's inability to swim leads to her drowning, shattering Anand's world.

Upon learning the full secret through the diary, Tanvi apologizes for her earlier treatment of Anand. The two form a genuine friendship, and Tanvi and Sunil begin collaborating more closely to help Anand recall his past. This marks the turning point toward his potential cure.

With Sunil's support, Anand starts remembering trauma and gradually improves. He and Tanvi grow emotionally closer, hinting at a romantic connection built on trust and care. The pair work toward a recovery that seems within reach.

Tanvi reveals her engagement to Karan, a match approved by her father, Khurana. The engagement complicates her budding relationship with Anand, since her father views it through the lens of doctor-patient boundaries rather than true romance. The family pressure adds tension to the hospital's dynamics.

Khurana learns of the relationship and vehemently objects, insisting Tanvi end the bond. Anand resists the hospital regime's oppression, pushing back against Khurana's authority. The clash escalates into a volatile confrontation that destabilizes the sanatorium.

In the escalation of control, Khurana performs a lobotomy on Anand to quell the rebellion and control the situation. The drastic act ends Anand's progress and deeply shocks Sunil, who witnesses the irreversible harm. The act marks a dark turning point in the story.

Sunil and Tanvi attempt to smuggle Anand out of the sanatorium so he and Tanvi can flee together. The plan is thwarted, leaving them to confront the grim reality of their choices. The attempt highlights the depth of their attachment and the system's brutality.

Facing an unbearable future for his neuro-disabled friend, Sunil makes the heartbreaking decision to end Anand's life by suffocating him with a pillow. He confesses the act to Khurana, a moment that compounds the tragedy within the sanatorium. Tanvi's world collapses as news of Anand's death spreads.

Overwhelmed by the news of Anand's death, Tanvi descends into insanity and is herself admitted as a patient in the same asylum, assigned the number No. 36. Dr. Khurana is shown as guilt-ridden for losing his daughter to a patient, a haunting end that underscores the film's moral weight.
