The concept has promise but I think it needs polishing.
Why 2 protagonists? ? It ?is usually better to focus the logline and script on one protagonist. ?Whoever gets the nod can have a sidekick/reflector character, of course and the sidekick can have psychic powers -- but not as powerful as the protagonist. ? (But the sidekick/reflector character need not be mentioned in the logline. ?The protagonist owns the spotlight in a logline, doesn't share it with friends or allies.)
Also the logline needs to indicate ?the gender of the lead because that's a primary piece of information ?movie makers are looking for in a logline.
In addition, ?the antagonist's objective goal needs to be bluntly stated: ?he's not just "hunting them down" -- he's out to kill them, right? ?The stakes for the protagonist are ?mortal.
Finally, the logline needs to focus on the objective goal of the protagonist in response to the threat of the antagonist. ?What must the protagonist do when he/she realizes the murderer is coming after him/her?
