A young man flees to a distant land and vanishes. His mother follows, certain she will find him, but in this unfamiliar place all certainties seem to crumble. In this story of love and loss, Wertenbaker explores passions simmering in contemporary Britain: the longing for identity, the despair of fragmentation and the fragile hopes of lives redefined. Credible Witness premiered at the Jerwood Theatre Upstairs of the Royal Court, London, 2001
