Shambhu is a 13 year old teenager caught in a transitional, adolescent phase. A phase when teens begin to qualify each other with labels and somewhat ironically, these childish labels often increase or decrease one's self worth. Never quite armed with the confidence of his more affluent friends, Shambhu falters consistently and invariably finds himself to be all thumbs down at the most crucial moments.
His inadvertent actions are detrimental to his teachers at school and at home too, Shambhu is a big cause of worry to his parents due to his constant goofy behavior. In the course of the semester, he manages to hit it off with a gang of friends. But that soon crumbles when misunderstandings caused by a high school girl impede their relationship.
Shambhu gets pushed into a world of peer pressure, responsibilities and adjustments. A world that his adolescent mind's just not prepared for. A huge fight with some local boys and a serious show down at school with his teachers deepens his crisis. Shambhu just wants to be happy and he realizes that the only way to do so is to run away from home.
On his journey of self-realization and discovery, Shambhu bumps into Vitthal, an extremely smart kid who belongs to a nearby fisherman colony. In Vitthal, Shambhu discovers an alter-ego, the sort of individual that he always desired to be. Shambhu is mesmerized by this new world he encounters with Vitthal. Everything is in such stark contrast to the world he had left behind. And everything worked just fine until a sudden turn of events force Vitthal and Shambhu to set out on a train journey in search of a place where they can find the freedom they desire, a place where they aren't bound by family obligations, a place that they will never have to leave again.
But destiny has its own way and this Kaccha Limboo finally rolls out having come of age after a life-changing journey!!!
