StoryLine:
----Hello is a tale about the events that happen one night at a call center. Told through the views of the protagonist, Shyam, it is a story of almost lost love, thwarted ambitions, absence of family affection, pressures of a patriarchal set up, and the work environment of a globalized office.

----Shyam (Sharman Joshi) is losing his girl friend because his career is going nowhere as he trudges his way around in a call center. His girl friend, Priyanka(Gul Kirat Panag), is also an agent like him at the call canter who is about to be snatched by an NRI techno geek.

----There is also the aspiring model, Esha (Isha Koppikar), who is hopping for the break that seems to be always already eluding her and the man about town, Vroom(Sohail Khan), who is into well, things. The housewife, Radhika(Amrita Arora), who is constantly at the receiving end of her mother-in-law and a beleaguered grandfather, Military Uncle(Sharat Saxena), who has been barred from interacting with his grandchild make up the rest of the call agents who see their worlds crumbling around them as the decisions of right sizing are conveyed by Bakshi(Dilip Tahil), the boss.

----It is a night when dreams will finally crumble. Or will it? For there is that call from God. Narrated as a tale within a tale as a beautiful woman meets the auteur narrator and promises him a story on the condition that he has to narrate it further.The movie "Hello" is based on "Chetan Bhaqat's one night @ the call Center", is the one remarkable story from Tales from a Thousand and One globalizing, urban, Indian Nights.
