When the world’s greatest superhero succumbs to an unknown disease, a convicted bio-terrorist tries to turn his engineered plague into a cure.

According to my understanding of this logline, the movie is about a mad scientist trying to engeneer a cure for his ex-girlfriend. He's a bio terrorist and she's a superhero but the movie still seems to be a boring research in a lab.

I think the antagonist/hero relationship is too complicated. It is unclear whether or not the ex boyfriend engineered the disease the MC currently has? It is also confusing how a super hero could miss the fact that her boyfriend was a bio-terrorist.

Lastly it comes across as if the ex boyfriend is an unlikely antihero main character, as he is the only one with a clear goal - to save his ex girlfriend. Otherwise what will the super-hero do in the movie?

And why does the convict want to rescue a ?super hero? ?What's in it for him? ?And what about the plague he engineered? ?Is this causally related to the super hero's affliction? ?Or is it something entirely different?

And presuming it's fatal disease, the logline might benefit from a ticking clock that escalates the sense of urgency. ?He only has a limited time to succeed before the super hero dies
