It's a mad, mad, mad world out there 
And everybody's worried they're going bananas…. 
Except the Krazzy 4 
Because they know they're already Krazzy!

Raja's anger knows no bounds, he'll hit out at the slightest provocation or even without. Intermittent explosive disorder is what the doctors call it. 'Sarphira', is what everybody else does!

Dr Mukherjee is your perfect doc – clean and orderly, not a pin out of place. So what's wrong with that? Obsessive-compulsive personality disorder, that's what it is.

Schizophrenic Gangadhar lives in the past…his mates are Nehru and Gandhi, Tilak and Patel! He's so busy fighting for swaraj and freedom; he's lost his sanity!

Cute Dabboo is everybody's pet. So what if he hasn't spoken for years? So what if he's frightened all the time? So what if he's autistic?

Dr Sonali treats them all. She has faith that all it needs is a little time and lots of patience to make them normal…to make them part of the mad, mad, mad world out there…

But is the Krazzy 4 ready for the world? And is the world ready for them?

Watch out! The Krazzy 4 are coming your way!! 
And yes...If you think they r crazy, think again!

Juhi Chawla is Dr Sonali: As a psychiatrist she knows what's wrong with her patients; as a sensitive woman she firmly believes that if you really want to make them well, you should treat them with your heart, not just your mind.

Arshad Warsi is Raja:Truly the angry young man! His blood boils, his fists clench and he's ready to beat the daylights out of anyone who upsets him in some way.

Irrfan Khan is Dr Mukherjee: He has decided that he's the Captain of the team! But so obsessed is he by the need to be in control of a situation, he doesn't realise he's totally lost control of himself and his mind.

Rajpal Yadav is Gangadhar: He's marching to a beat only he can hear; he's fighting for a cause that's long over. But in his muddled mind he's still fighting for Swaraj; still hobnobbing with the likes of Nehru and Mahatma Gandhi.

Suresh Menon is Dabboo: Cute and adorable, he's everybody's pet and however far-gone the rest may be, when it comes to Dabboo, everybody's super protective. Even if he can hear and understand, Dabboo refuses to speak. And nobody knows why!

Dia Mirza is Shikha: As a TV reporter she controls the news on the channel, but as a woman she's unable to control the unruly and unmanageable rage of Raja - the man she loves.

Rajat Kapur is Industrialist R K Sanyal: who's also Dr Sonali's husband. But in his quest for power and money he takes a step that will have alarming consequences for his wife and her patients - the krazzy 4!

Zaakir Hussain is Srivastav: He is so neck deep in illegal activities that now he'll stoop to anything - even kidnapping and murder - to keep him ahead.
