When an NYC lawyer fails to brush off his emotionally unstable one-night stand, he must protect his family from her frenzied attempts to replace them.

Very good, Richiev.? A clever play on words (in this case, the rhetorical device of antithesis) can strengthen the impression a logline makes.

However, the plot "Fatal Attraction"? ?is not about a peccant husband having to defend his family against a? woman who seeks revenge.? It's not revenge she wants. She just? wants him for herself.? She's obsessively, pathologically possessive.

It sounds like a great thriller, ?the only thing that strikes me is that it sounds too much like "Fatal Attraction" (1987).?So what is different with this one?

The nightmare part is important to imply the genre - she becomes far more than? just a nuisance in the movie...

"When his one-night stand becomes a full-time nightmare,?an?NYC lawyer must defend his family from his scorned lover's attempt at revenge."
