Ambassador Davis' attempts to secure a £2 billion helicopter contract for Britain are hampered by the arrest of a human rights activist and the accidental shooting of an Ibex, the national animal of Tazbekistan.
The arrival of an insensitive member of the royal family coincides with the escape of an outspoken political dissident.
An anti-government rebellion threatens the stability of Tazbekistan and Ambassador Davis makes an uncharacteristically bold decision to try and meet the rebel leader.
