Secrets & Lies (1996)

Cynthia lives in London with her sullen street-sweeper daughter. Her brother has been successful with his photographer's business and now lives nearby in a more upmarket house. But Cynthia hasn't even been invited round there after a year. So, all round, she feels rather lonely and isolated. Meanwhile, in another part of town, Hortense, adopted at birth but now grown up, starts to try and trace her mother.
