May Day! is a feature-length documentary which follows Oxford's thousand-year old tradition of May Morning, the largest celebration of its kind, regularly attracting over 15,000 people each year. It is a collage-like portrait of the tradition, attempting to find out how the celebration has survived the separation between the land and its people, what the pagan festival means thousands of years after its inception, and how it shapes and contributes to our nation's sense of self.
