When a researcher creates a technology that can see anything from the last twenty four hours, a former FBI profiler must find him before the private assassins of a corrupt politician he exposed.

JasonF:

You are correct that usually a logline should not contain spoilers.

However, after reading your comments, it still seems to me that the scientist has more skin in the game. ?The profiler only has his reputation at stake. ?The scientist has his life. ?For the purpose of dramatic suspense in a thriller movie, life always trumps reputation.

And he still seems to be the more interesting character with the greater character arc. ?Describing him as "naive" means he has a lot of growing up to do in coming to terms with the consequences of his invention -- and his own talent. ?In comparison, what's the character arc of the FBI profiler other than getting to vindicate himself, prove to everyone else he was right all along.

?(Vindication is a worthy dramatic motivation, of course -- but in this story, ?I get a sense of a stronger emotional catharsis and cognitive closure in the arc of the scientist. ?The story motif of the "Sorcerer's Apprentice" comes to mind.)

And the hook of your story is the technology -- not the profiling. The ability to have an omniscient view of recent events?completely overwhelms the importance of the role of the FBI character. ?Which is not to say the FBI character cannot be a key player , but the technology is the sizzle, the strongest selling point of the concept. It's the McGuffin, the thing everyone in the story wants.

(Minor quibble: he's lecturing FBI trainees not "students". And if he's lecturing, he's still actively employed by the FBI. He's just been pulled from field work. )

fwiw

There were some movies which have multiple characters and various POV.

However, I still believe that we should establish a protagonist at whom audience
can sympathize since the very beginning.

We could and should develop story background for other roles, too, but if the weigh
of the story is distributed towards multiple characters, I think it would only confuse
tire the audience.

So, a heavier concentration on one main protagonist must still be present. If the scientist
is the main character, then the profiler shouldn't be mentioned as another Subject. He must
be put as object.

"When a researcher creates a technology that can see anything from the last twenty four
hours, he must escape from the pursue by agents hired by a corrupt politician to kidnap him,
while he is accompanied only by a retired FBI profiler."

Is this better? Hahahaha
