Meghna is a woman who experiences emotional distress following personal losses, including her mother's death and rejection by her fiancé. In search of an escape, she seeks sleeping pills from her doctor father to end her life. However, she is approached by Ananda Kar, the founder of the Hemlock Society, an organization that offers training on various methods of suicide. Ananda persuades Meghna to attend a three-day workshop at the society, which operates from a film studio and features instructors specializing in different suicide techniques.
During her time at the workshop, Meghna meets other participants and experiences a series of events that alter her perception of life. Over the course of the training, she begins to appreciate the value of life and empathizes with the struggles of others. On the final day, Meghna confesses her desire to live and admits that she has developed feelings for Ananda. Ananda reveals that he suffers from lymphocytopenia, a condition that leaves him with only two years to live. This revelation reinforces Meghna's newfound understanding of life’s importance.
Meghna leaves the Hemlock Society and returns to her father, having undergone a transformation in her outlook. Six months later, she reconciles with Ananda, who is hospitalized following a blood transfusion. The film ends on a satirical note, with Meghna's former fiancé, now despondent, becoming a participant at the Hemlock Society.
