Maggie O'Brien, a nurse and medic on a SWAT team, has a thirst for justice, and a chip on her shoulder. She lives in the shadow of her father, a famous (or infamous) cop. Is she more like him than she wants to admit? The question hits home when Maggie feels the desire - as all police, nurses, doctors and medics sometimes do - to dispense her own brand of justice. Soon she finds evidence that someone else may be acting on the same desire. Her search for the truth is a searing tour through the shades of gray between the impulse to heal and the urge to punish.
