Set right before the fall of Thailand's old capital, Ayuttaya, Bang Rajan draws on the legend of a village of fighters who bravely fended off the Burmese armies. With no support from the Royal army, the villagers drives the invading Burmese away many times until their names have become legendary during the time. As each subsequent battles becomes fiercer, the villagers tries to forge a canon to battle the enemy in a final battle where everyone, women and children included, die in combat.

This is the story about the resilience shown by the Indians when they were under the British Rule. They are already taxed to the bone by the British and their cronies, but when Jack Russell announces that he will double the Lagaan (tax) from all villagers, they decide to oppose it. Leading the villagers is a handsome young man named Bhuvan, who challenges them to a game of cricket, a game that is to be played by veteran British cricket players, versus villagers, including Bhuvan himself, who have never played this game before, and do not even know a bat from a piece of wood. As the challenge is accepted, the interest grows and attracts Indians from all over the region, as well as the British from all over the country - as everyone gathers to see the 'fair play' that the British will display against their counter-parts, who are aided by none other than the sister, Elizabeth, of Captain Rusell.

The Countess is called away to tend a sick friend and imposes on the General to accept her daughter Marcilla as a houseguest. Some of the villagers begin dying, however, and the General's daughter Laura soon gets weak and pale, but Marcilla is there to comfort her. The villagers begin whispering about vampires as Marcilla finds another family on which to impose herself. The pattern repeats as Emma gets ill, but the General cannot rest, and seeks the advice of Baron Hartog, who once dealt a decisive blow against a family of vampires. Well, almost.
