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.

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
