First of all, I think you’ve got an great idea for a compelling story. Especially as it’s based on the life of real twins. Truth is stranger than fiction — and more interesting.

However, loglines and plots are not about a choice a character has to make.? Rather, loglines and plots are about the initial choice a character makes that commits him to achieving an objective goal.? One that may eventually bring him to the dramatic crossroads entailed in your logline.

So what is the dramatic choice the twin makes upon his release? (BTW: I assume that the story kicks into high gear, when the innocent twin finally gets out.) Well, if he chooses to forgive him at that point — fine. But that’s the end of the story. He’s resolved his dilemma. FADE OUT:… CREDIT ROLL

So, I assume his initial dramatic choice upon being released is to seek sweet and sour revenge.? Hence, this as? a possible logline:

Freed after 26 years for a crime he didn’t commit, a man sets out to get revenge on the man who did, his twin brother.
(25 words)

One question: What kind of revenge does he seek? To kill his twin? Or to prove his guilt so that the real criminal can go to jail?

Whatever, the dramatic journey he takes may lead him to the climactic crossroads where he finally has the opportunity to exact revenge. Or not.

That could be the moment of emotional and spiritual truth when he chooses to forgive.

Finally, I suggest tagging it as biography rather than drama to designate that it’s based upon a real people , real events.

Hope this helps.? This is a movie I would like to see. Best wishes with your writing.
