The Earl of Gilleigh, whose dyspepsia has been severely aggravated by the news that his ill-tempered wife Sophronia is due to arrive from abroad, is startled by the noise of a burglar and enters the room to find his long-lost brother, Warren Ellis, voraciously helping himself to a meal. Warren accepts the Earl's proposal that the two trade identities, and while he remains in Gilleigh, the Earl retreats to his country estate. After meeting Sophronia, however, Warren quickly follows his brother to the country, where he is entranced by a lovely shepherdess named Rosalind.
