After an epidemic breaks out, causing the violent deaths of its victims, a recently widowed forensic scientist working for the CDC must lead his team to safety while he completes development of a cure, before it claims his daughter as its next victim.

The only thing I was not clear about is, is the epidemic causing people to die violent deaths... or are they being turned into something that causes them to attack people, resulting in violent killings of others.? I wasn't sure how to fix the first sentence to clear that up for the reader. That way if people are into zombie attack type movies it is clear for them. If this is about people dying gruesome deaths as they become ravaged with some disease or flesh eating virus... people that are into that know what they are about to watch. Good luck !

With a minor tweak on the grammar and clarification to the reader I think you will have a nice, precise logline.

Thank you James! Still struggling indeed and I have already lined out the story and writing my screenplay. If you want to read it when it is finished that would be great!

Awesome! I would be glad to review it. I have found that my best investment was a cork board, pushpins and index cards. I can make small notes about various scenes, key actions, character introductions and place them in the order that I anticipate them going and then I can easily manipulate it. I know you can do this electronically, but physically seeing and touching it, helps me feel more involved. And I can always jot/scribble things that might be critical for a character to do and say. SUPER easy to visualize it in a matter of seconds.

For some reason can't rate this, I give 4 stars, and like James Barber's tweak. Hope it goes well for you!

Great concept!
