What is his new friend? Man? Golf ball?

Why does the talking golf ball want revenge? What happened that made them separate, and is it something the talking golf ball really needs to get revenge with?

After years of success, a talking golf ball is (unknowingly?) (replaced? rejected?) by his partner. Down on its luck, the ball seeks to return to the golf scene no matter the cost! <- This could make it interesting, cause if shows the determination of the ball, and how far it is willing to go. When it meets the "friend", it will make us question the intentions of the ball. Does the talking golf ball see this "friend" as friend or a means to an end. And is revenge its ultimate goal? or just the enjoyment of the game? Good path of discovery in this, not to mention making the golf ball seem more dimensional.

There are a few grammatical errors in this, and there is a lot of exposition that is not really important to the plot of the story. Is his being gay really relevant or at all a key item of the story? Or just his character? Logline should give more the idea, than a full description of the character. Usually when I go on business trips, I don’t bring my family, so the whole business convention doesn’t really do anything for me. More than anything, it seems like you are trying to deal with two big stories: 1) Being gay and having to hide this fact because of Russia’s ridiculous and narrow-minded view of homosexuals; 2) Dealing with a family that is demonic (or whatever). You could honestly split this up into two separate stories. The first is uninteresting and as pointless as Russia’s homophobia. There is no story, as that would suggest that gay men can only hide their sexuality through others, and that to me is nonsense. I love woman, but can go to another country without hitting on any. Could be more interesting if the businessman has a love interest there, or meets someone, and they must hide their longing for each other.

The second story is interesting, but tough to find a situation plausible for hiring an estranged family to pose as your own. Why can’t he use his own family? Where did he find this family? What made him think: These people could totally work. I would try and focus on one central idea to the story you have in mind; maybe give me more details of what direction you want to go.
