The park is a ubiquitous urban feature that sees all manner of human life pass through its gates. With its ponds and pathways, playgrounds for children and arbours for addicts, it's the place where illicit assignations are made and afternoons are ambled away. This portrait of the park was built up over the course of a year from the funny, exotic and erotic stories to be found among the trees and flowers.

In the first of two programmes, summer turns to autumn and two lovers begin their tragic story.
