When her father drowns she goes to live with Jenny Wren. Lizzie rejects the advances of schoolmaster Bradley Headstone and opposes the attention of Eugene Wrayburn, although she loves him, because they come from different classes of society. She runs away from London to a mill up the river. Wrayburn succeeds in finding her and is followed by Headstone who attempts to murder Wrayburn. Lizzie rescues Wrayburn and later marries him.
