Actor Thomas Higgins has taken on the persona of one of his well-to-do stage characters, ex-Bengal Lancer Colonel Anthony 'Sahib' Carleton. His family has too followed and are now known as the Carletons. They are doing this in an effort to live off the rich and wealthy who are willing to flaunt their riches on the Carletons. On the train to London from the French Riviera from where they were thrown out by the local authorities for their grifting ways, the Carletons meet Ellen Fortune, a lonely elderly woman who has recently come into a fortune. Miss Fortune invites the Carletons to stay with her. The Carleton's daughter, George-Anne, sees this situation as the permanent answer to their life: they lead a straight life with Miss Fortune, including getting jobs, in the probability that she will deed her entire estate to them. In their time with Miss Fortune, the elderly woman may have more of an effect on the Carletons than the other way around.
