As the Games get ever nearer the Algerian Olympic team threaten to boycott the Games after discovering that the Shared Belief Centre does not face Mecca.

Ian (Bonneville) and his team have just hours to find a solution that will keep everyone happy. Head of Infrastructure Graham Hitchins (Theobald) ends up accompanying Ian to a crucial three-way teleconference with Sebastian Coe, the British Foreign Office and the Algerian representative, Dr Benhamadi. No chance then, that events will end up veering badly off track.
