Hi Michael.

This is a vast improvement on the previous drafts as there is a clear link between all the elements and the log lines is well structured.

I would reduce the word count to ease the read and change “…pushes to cover up the incident…” to a specific action as that is too vague for a reader to understand exactly what he is doing.

The word “…rapists…” is confusing out of place and seams unrelated to the plot. I understand that this is part of the story but for the logline purposes better to omit it and reserve any of these descriptions for a synopsis.

My try:
After an overambitious manager gets infected by a primordial fungus that killed his Arctic oil rig crew he must avoid the media and stop the spread of fungus throughout the local hospital by saving the sole survivor that holds a cure.

Good advice above I would add though that even in the revised logline you havn’t yet described a plot for a story rather as Richieve said still a situation.

Have a read of Karel’s logline writing guide here:

But in short your salesman (no need for vacuum) needs something to happen to him (either someone else’s action or and event) to push him to want to achieve a tangible goal also best to have an obstacle for achieving it.

What makes him need the goal?
What is his goal?
How will he achieve it?

Hope this helps.
