Mahadev is one of the few educated young men from Sajjanpur. His ambition is to be a novelist but finds it easier to make a living by writing letters sitting next to the post office. His ability to write persuasive letters makes him popular with the largely non-literate population of the town. Aware of this power, he soon uses his talent to manipulate people with amusing and sometimes not such amusing results.

With this as the narrative frame, Welcome to Sajjanpur shows in an entertaining, musical and comic way, characters and events that are at once hilarious and poignant. A delightful satirical take on a contemporary Indian village.
