When a lonely pensioner finds an abandoned baby on her doorstep, she has no idea that the child is the illegitimate offspring of a member of a royal family.

But the secret is soon out. The authorities and the press pull out all the stops to find the missing child; but so does Charles, a violent man with his own agenda who, it soon becomes clear, will stop at nothing.

The old lady and her best friend take to the road in an attempt to keep the baby safe. They are soon on the run in a foreign country, with no idea what to do next, where they're going, or what will happen to the innocent foundling.
