Just finished watching Stephen King's movie "A Good Marriage" about a woman who finds out her husband is a serial killer. Not brilliant - lots of room for improvement, with or without a gender reversal.

good first try, maybe research what it is and try again - a logline is like a hook! 25 words or less best of luck https://screencraft.org/2020/02/26/the-simple-guide-to-writing-a-logline

Hi Nadir, this is a cool premise, but adding some detail about what happens to the man after he discovers that his wife is a serial killer would make it much stronger. You could start, "After a man discovers that his wife is a serial killer, ..." and then add in something from the rest of the story.

Hello, Molly. Thanks! I will consider this option:)

Like ah flilp to the Green River Killah, what wha wha what? Green River Killer, Gary Ridgway, was the ultimate chameleon. 3 wives - 20 years of killing. He got away with more slayings, for a longer period of time than any other American serial killer. To his acquaintances and family, he was reserved, even-tempered, ordinary. He was a "model neighbor" and even "overly friendly," observed one slightly annoyed neighbor. "When I was out in the yard, I couldn't get anything done because he wanted to talk all the time," Seattleite Paul Winkle. They credit his bloody longevity to his cautious sense of self-perseverance — a rare trait among compulsive killers. Ridgway saved his own skin for the final time when he struck a plea deal in 2003. He would show investigators where he'd left the bodies in exchange for avoiding the penalty he'd seen fit to deliver to so many innocent women. Ridgway killed so many sex workers during his 1980s heyday, he couldn't remember them all. Initially, he was convicted of 48 murders...49? 50? Estimated 100+ though he never killed his wives (3 of them), his cautious nature made him self-preserve first.

There are a lot of such sad stories Juan

Nadir Akhmerov I disagree. There are similar ideas and genres, but each with a different way of telling that story: though there are a few movies that are very similar, though that's a very small list: think Matrix vs eXistenZ, or Armageddon vs Deep Impact, or Turner and Hooch vs K-9, or Antz vs A Bug's Life, Olympus Has Fallen vs White House Down... .

Juan DnDink. I just misunderstood you at first. Naturally, there are a lot of similar films and genres.There are many movie plots similar to mine. But my story is still written differently, and there are many original moments in it.

I like the logline - but perhaps consider changing "but then" to "until" - it may flow better. Good luck!

The logline gives no indication of what happens when the man discovers his wife is a serial killer. Something like this would work better: "When a happily married man discovers his wife is a serial killer, he tries to rehabilitate her without letting on that he knows about her crimes.
