Other forms: cutting to the chase; cuts to the chase
To cut to the chase is to hop past anything secondary to the core issue. It's diving full-tilt into the main problem or topic.
One likely origin of cut to the chase comes from action films, which frequently include exciting car chases or scenes of heroes running after villains. To get to that stuff, you have to do a little bit of explanation about why it's happening, but an action movie won't be very fun if it's bogged down in long discussions about the situation. So it might be necessary to advise a writer or director to skip all that messing around and just cut to the chase.
