Set against the backdrop of intense romance "Kyon Ki" is a tragic tale of two ordinary sane people's rebellion against the insane medical ethics and medical system as a whole.

Young and charming 'Anand' (salman khan) is in love with 'Maya' (Rimii), a cute bubbly girl. Maya too loves Anand but is always out to play some or the other prank on him. Anand and Maya are planning to marry and have a family but destiny has some other plans for them.

Maya's prankish nature results in a freak accident in which she dies!!

Unable to overcome the shock, Anand losses his mental balance. He is sent to a mental hospital... Here he becomes just another patient: patient no. 36.

Strict and old-fashioned Dr. Khurana (Om Puri) is the head of the hospital who believes that brutal forces and oppression is the only way to tackle insane patients.

Where as Dr. Tanvi (Kareena Kapoor), the young petite daughter of Dr. Khurana, and Dr. Sunil (Jackie Shrof) do not approve of Dr. Khurana's inhuman attitude towards the patients. They feel that patients should be treated with compassion, not aggression!!

Anand retaliates against the strict hospital regime and rebels against the system. He breaks many rules leading to a series of bitter-sweet incidents.

Doctor Tanvi takes up the case of 'Anand' and treats him in her own compassionate ways. This brings her close to Anand and soon Anand regains his mental balance and gets complely cured. But during the course of this treatment, Tanvi loses her heart to Anand and he too reciprocates her feelings.

When Dr. Khurana comes to know about this, he is outraged. In order to separate the 'couple in love', he refuses to accept that Anand is cured and takes him to 'shock room' where Anand is given electrical shocks and transformed into 'vegetable'.

Kyonki Dr. Khurana loves his daughter and has attitude problem....
