In the throes of the Russian Revolution, down-to-earth Nadya gives little importance to thoughts of romance. When love does come to her, it is tainted by his lingering infatuation with a mysterious beauty. Fed up with loneliness, she throws caution to the wind. But when her rival comes back into his life her identity threatens to shatter more than just their budding relationship.

Hi, from what I have read an ideal logline is 25 words maximum. I often struggle to hit this, but while you need to set your world, I do think even if you do go over 25 words you still want to make this one a bit shorter. You talk about the love triangle, then the antagonist coming back. In the logline I'd just go for the essence, saying, it's a girl (protagonist) who has to get a guy (goal) who is infatuated by another beauty (obstacle)...set in Russian...blah. As it is, this looks more like a paragraph synopsis to me. I hope that's helpful. Best, Andy
