Susan, Millie, Lucy and Jean have returned to post-war domesticity, modestly setting aside the part they played in the Allied victory. Their brilliant work at top security HQ Bletchley Park helped crack the codes used by the German military, producing crucial intelligence that shortened the war. Susan hears about a string of unsolved murders in London and her old Bletchley spirit is ignited and she spots a pattern of behaviour in the killer that no-one else has. Unaware of her background, the police dismiss Susan’s theories causing her to realise that the only way she can solve the murders is with the help of her friends. A race against the clock ensues as the women try to outwit the police and the culprit - can they rekindle their singular expertise and work out the killer’s next move before he strikes again?
