Just some ideas for loglines:

1) After being gifted its own sapience, a man's wanton lust for violence reveals itself through increasingly graphic proclamations of its own existence in the face of the man's equally impassioned morality. 

2) An archetypical sci-fi villain discovers that they are merely a character in a screenplay, and within the confines of this restriction, questions the nature of the world they terrorise, and of themselves.

3) While seeking to remove herself and her struggling family from poverty, a mute woman inserts herself into an infinite, infinitely complex multiverse, and the covert, last-gasp effort to save it from imminent implosion.
