When a manic-depressive sharpshooter’s mother is assassinated, he marauds a criminal empire for the elusive hit-man responsible.

I think it could be beneficial to be more specific about the nature of the antagonist - Who does the hit-man work for? Is the hit-man the antagonist, or was the hit carried out on another person's orders? Expanding the role of the antagonist a little more in the logline will help to personalise the stakes more fully.

As Dkpough1 said. ?Bipolar has replaced manic-depressive in psycho-lingo.

?I have a concern about the wording, that the character is defined in an adjective phrase, rather than as part of subject of the sentence. ?So instead of?"When a bipolar sharpshooter's mother is assassinated, he..." ?I suggest "When his mother is assassinated, a bipolar sharpshooter...."
