When Shaun arrives with his pregnant wife, commanders order him to take her home while a soldier volunteers to stay and watch. Tessa insists on performing and claims she can dance the Spirit of the Peacock, but Yelena and others insist she can't possibly know the country's most difficult ethnic dance. Professor Knapp, the leading expert, appears to recruit Madam Burton, turning the rehearsal into a proving ground. Critics warn Tessa she’s one misstep from expulsion, and with the expert watching she now must prove her claim or face being booted.
