The traces left by the era of the samurai are still with us today. From this rich history of this ancient warrior culture comes a tale of honor, vengeance and redemption with a dark, sense of meaningless fatality. It is the origin story of a cursed vigilante, Ai, hell-bent on disposing those responsible for her clan's demise. Inspired by the great tradition of samurai cinema, Ai is an exploration of the era of the samurai and explores the themes of dormant fury for those who have lost loved ones and are driven to the point of madness with revenge.

The Winter Butterfly is a story about passion and love, depicting Matsunaga a samurai, as a corrupt oppressor rather than a hero. With the emergence of a new system during the Meiji period, many things changed in Japan for the sake of progress. The story told in four parts is related to the seasons of the year, which can be scorching, amenable, cold or unpredictable. All evoked by Stephen Warbeck's beautiful and sensitive score.
