The film revolves around a successful advertising campaign manager named Arjun Dutt (Siddharth). During a routine medical check-up, he discovers that he is HIV positive. He is totally devastated. Instead of facing the truth and telling his pregnant wife and son, he runs away from his home and job.
While wandering like a beggar through the trains, he is robbed by a group of thugs who beat him up and leave him for dead. Then a doctor (Pankaj Kapoor) takes him to his hospital. After coming to his senses, Siddharth tries to go but is stopped by the doctor. The doctor conducts another test to find that Siddharth is, actually, HIV negative.
Siddharth returns to his family and while searching through his doctor's records discovers that another patient, also named Arjun Dutt (Pawan Malhotra), is HIV positive while he has always been HIV negative. Now, he is faced with the dilemma of telling the currently happy man the truth, or remaining silent.
