Two blood testy women killer brothers, must face each other when One fall inlove with a woman

Please any suggestions or sample, thanks

You might try to re-write the logline using different words. It took me about 5 tries to unravel your sentence. That is not a criticism of the premise, it's just that the logline is a bit hard to read. And that is what re-writing is for. Keep working on this, and good luck.
