 Early 20th century England: while toasting his daughter Catherine s engagement, Arthur Winslow learns the royal naval academy expelled his 14-year-old son, Ronnie, for stealing five shillings. Father asks son if it is true; when the lad denies it, Arthur risks fortune, health, domestic peace, and Catherine s prospects to pursue justice. After defeat in the military court of appeals, Arthur and Catherine go to Sir Robert Morton, a brilliant, cool barrister and M.P., who examines Ronnie and suggests that they take the matter before Parliament to seek permission to sue the Crown. They do, which keeps Ronnie s story on the front page and keeps Catherine in Sir Robert s ken.
