Salting the Battlefield

The film follows Johnny Worricker (Bill Nighy), a former MI5 analyst, and Margot Tyrrell (Helena Bonham Carter) as they evade capture by MI5 after their flight from Turks and Caicos, hopping around Europe to stay one step ahead. They separately make plans for the future: Worricker sets an encounter with Prime Minister Alec Beasley (Ralph Fiennes) at 10 Downing Street, while Tyrrell prepares to leave for Hong Kong to start a new life.
