Antonin Baudry wrote and directed the French film The Wolf's Call (Le Chant du loup) from 2019, now streaming on Netflix. You might think from the movie's title that we're in animal/nature territory, or even in horror movie territory, but the plot of the film is about as far away as you can get from either genre. It's a thriller about two ballistic missile submarines, one of which (the Titane) has been commissioned to take out the other (the Effroyable) that has been commanded to launch one of its nuclear warhead ballistic missiles against Russia in response to a (presumably) Russian launch against France from a decommissioned Russian nuclear sub (the Timour III). Unfortunately, it was not the Russians who were responsible for the latter; it was a terrorist organization called Al-Jadida (who illegally bought the decommissioned Timour III) that launched a ballistic missile (without its nuclear warhead) against France so that France would think it was a Russian attack. The idea being to start a nuclear war between major world powers.
The film's focus is on the sonar expert Chanteraide (very well-played by François Civil), whose excellent sense of hearing is crucial to tracking down the position of the Effroyable and ending the threat of nuclear war. I was previously unaware of the importance of sonar experts to submarine activities. I knew that subs rely on sonar to detect objects around them, but I didn't know about the importance of sonar experts to that onboard activity, but it makes sense that such experts are needed to interpret the sonar printouts and graphs. The "wolf's call' is an active sonar alarm that indicates that a submarine is detected and targeted; the term 'wolf's call' is navy slang for this event.
I found the film to be very good; it has action, suspense, and the plot complexities that characterize a good thriller. It gave me a new understanding of life onboard these types of submarines and a new appreciation of the men who risk their lives in the service of their countries. I have climbed down a steel ladder into a small submarine once in my life, and climbed right back up again; the claustrophobia was overwhelming. Kudos to the men (and women) who manage to live their lives at sea in this way. I could never do it. If something goes wrong, e.g. as in this film where one of the subs is hit by a missile, it's game over for all onboard. The dead are honored in a poignant scene at the end of the film; I found myself very moved by that, a good indication that the film managed to engage viewers' feelings in addition to being a good thriller.
