A “sparrow” is the term for a Mata Hari style secret agent, trained to seduce men in pursuit of secrets. Ballerina Dominika Egorova (played by Jennifer Lawrence) is inducted into this life by her uncle Vanya (I know, I know; the Chekov references could be subtler), a spymaster, when her ballet career is cut short by a serious injury. Trained at spy school by the cynical Matron (Charlotte Rampling) and directed by General Korchnoi (Jeremy Irons), Dominika is soon thrust into the cut and thrust world of espionage.
Andrew Haigh’s low-budget film follows a week in the life of an elderly married couple Kate and Geoff (played by Charlotte Rampling and Tom Courtenay), who are about to celebrate their 45th wedding anniversary. They live a quiet life in rural Norfolk, with no children in their life but an Alsatian called Max and a few old friends.
