Princess Caraboo

In Regency England, a beautiful young stranger named Princess Caraboo (Phoebe Cates) is found in the fields, speaking a language no-one can understand. She is tried for vagrancy and eventually welcomed by the Worrall family, who believe she is a genuine princess from a far away land. However, local reporter Mr. Gutch (John Lithgow) investigates her claim, and eventually discovers that she is actually Mary Baker, a servant who had worked at the Magdalene Hospital in London.
