McNally and Swarek arrest a minor for stealing an ice-cream truck. Swarek believes that the theft was an act of rebellion; McNally who believes otherwise is sent out with Shaw to pursue leads. However, they're shortly called to a residence where a mother is reporting her daughter missing. McNally's instincts lead her to believe that two girls were abducted from the park and the minor they have in custody managed to escape. Her instincts are correct as McNally and Shaw trace the missing girl to an abandoned recreation center. Shaw is shot by the perpetrator leaving McNally by herself. After finding the girl, McNally comes face to face with the perpetrator and is forced to kill him in self-defense. She is in shock and goes to see Swarek, and ends up almost sleeping with him. Also, Epstein and Peck are forced to deliver a baby after a woman goes into labor. Complicating issues arise after the officers realize the woman suffers from agoraphobia and refuses to leave her residence.
