Based on 'Cop Car' by Keith Urban.

You and your new girlfriend, Robin, had trespassed into private land one night. It was a calm and quiet place where you could sit on the tailgate of the car together and watch the planes take off. You thought you had all night, but then some cops pulled up. The blue and red lights flashed as Robin laughed, bringing out the freedom in her eyes. You were too busy watching her to worry about going to jail. When the cops had you both in the back of their car, Robin leaned over to you. "Running for it would make a great story, wouldn't it?" And the happiness and freedom in her eyes, despite being in the back of a cop car, made you realise you were falling in love with her.
