Glamorous Alice Keach is one of 1930s London's foremost hostesses.
Despite humble American origins, she has secured her place in high society through marriage to one of England's wealthiest bachelors. But Alice has a secret. Its roots run years back, and miles away, to the dust-blasted prairies of Kansas.
It corncerns a lost little boy left under the haphazard guidance of an eccentric uncle.
Now, a visit from America looks set to blow apart Alice's glittering pre-eminence forever.
