When Paris, Ari and Simone learn that a music video is being recorded at Saturdays, they decide they have to be in it! But they have to age up to look 18.

London begins his new job as the rink's DJ and starts to embarrass Paris. So, Paris hatches a plan to turn London's world upside-down so her world can be right-side up again.

Paris asks if Simone and Ari can work at her parents' baking biz. Cal and Deb reluctantly agree, but before long, Paris is working overtime to clean up her friends' mess.
