Harley Quinn, with her signature blonde and blue pigtails and red and black outfit, is shown in a series of quick cuts. She blows a large bubble with gum, then appears in a dimly lit room with her hands on her head, followed by a close-up of her face, then she holds a baseball bat, and finally, she is seen laughing maniacally in a dark setting. The scenes are set in various dimly lit, urban environments.
