Ouch! Good work! Great premise ! BUT... out with the shears ! First, imply the genre, don't state it outright. Treat it like a movie, give the audience clues - we love a puzzle, let us work stuff out.
"When Emily, a proud single mom, is locked in a car rigged with explosives, she must drive the car into the heart of New York or the kidnappers will execute her 5 year old twins.
(I think personalizing the word 'family' is always good). Is 'pride' her flaw ? Is that the negative quality she must conquer in order to achieve her goal and save her family ? if so, it's the right adjective. If not, what is her flaw / wound / event from the past that is causing her all this grief ? Great work though! Nice one. Script written yet or just an idea ?
