Jinxter tells the story of a man on a mission to save the fictional land of Aquitania from the looming threat of evil witches.

The game is a science fantasy comedy set in the fictional country of Aquitania, which bears a strong resemblance to early-to-middle 20th century Britain.

The Guardians, who are members of ARSE, the Association of Registered Stochastic Executives, are described as liking to wear herringbone overcoats and eat cheese sandwiches.

The player character is, pretty much accidentally, recruited by the Guardians to rescue his kidnapped friend Xam, retrieve the charms, fix the Bracelet, and then use its powers against Jannedor to kill her and destroy her castle, thus defeating the witches and restoring luck to Aquitania.

However, due to a falling out between them, the whole text had to be rewritten in three weeks by Michael Bywater, who had previously written the What Burglar magazine for The Guild of Thieves and then helped with Corruption.
