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:)

There are a lot of such sad stories Juan

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.
