Sean Metcalfe is a family man first and salesman second. When a tragic car accident sets off a series of events, Sean will need to come up with the ultimate sales pitch to keep his family together.

What does the car accident have to do with the sales pitch? How are the stakes of a failed sales pitch the loss of his family?

Hi,

I find your longline quite conflicting. The start sounds like a tragedy but the second half almost sounds like a scam that your protagonist intends to pull off?

Is this a comedy or drama?

Perhaps you can focus your longline on the story you are telling.

What was the tragedy? I assume death.
Why is the family threatening to fall apart?

Maybe try to use a formula along the lines of:

Following a car accident in which [something happens], a family oriented salesman is forced to [do something] in order for [the desired outcome to occur].

Good luck

Don't reveal the name of your protagonist.
