After assassinating the German ambassador in wartime Casablanca, an intelligence officer marries his French Resistance partner. But when she is suspected of being a Nazi spy, he must find out her true identity.
What is interesting about this film in terms of loglining is that the second sentence constitutes the MPR (Midpoint Reversal) that occurs an hour into the film. The film is essentially the splicing together of two one hour episodes set in two 2 locations. The 1st hour is set in Casablanca, the 2nd in London. Everything that happens in the 1st hour is prologue and setup for everything that happens in the 2nd hour.
It’s also worth noting how the IMDB summary phrases the post-Casablanca episode: “When they reunite in London, their relationship is tested by the pressures of war.” Which is hiding the game ball,; it leaves the reader utterly clueless as to the main action of the 2nd half, the dramatic problem the protagonist must solve. Something a logline should not do.
