What do you conceive as the hook of the story?
What makes this different from, makes it stand out from all the other films already made about plagues and epidemics?
Why must the protagonist be an investment banker? ?What's so dramatically special about his profession in relation to the epidemic? ?How does being an investment banker make him a sympathetic character? He's in the over-privileged 1% with money and access to resources to better his odds than the other 99%. ?So why should the audience (most of whom are in the other 99%) care about him?
How does"attempts at redemption" translate into a concrete objective goal? ?What specifically must he do? His efforts may be "fruitless" but what exactly he is struggling to do, what's his game plan to survive? ?And does it include saving others?
Take as an example "Schindler's List": ?the protagonist's redemptive act for exploiting Jewish labor during World War 2 translates into the specific, concrete objective goal of saving as many Jews as he can from the ghetto and Auschwitz. ?He risks all, spends every pfennig he has to save others.
