Episode 1 (of 5): Beginnings
The River Thames has run softly through Piers Plowright's largely unplanned life. In this five-part series, he visits different points along its course where his life has crossed the great river.
In this first programme he seeks out the river's source in a dry field in Gloucestershire and finds his way, meanderingly, to Lechlade, where he spent family holidays as a child. Along the route, he meets people who spend their lives by the river - and takes the occasional dip.
Produced by Alan Hall.
