When Maddie and London schedule their Sweet-16 parties for the same day, Maddie tries to talk London into rescheduling hers (It's not even London's birthday) for a different day, since they share the same friends. London doesn't budge. On top of that, she plans a spectacular party at the Tipton, with gifts for the guests (like plasma TVs) and great food, while Maddie, well...you know Maddie. All the guests (except Zack) show up at London's party for the free stuff, while only Zack makes it to Maddie's party ('cause we all know how much he loves her). But Maddie isn't the only one having a lousy time. London discovers that her 'friends' are their just for the hand-outs, and she also must pacify her parents who aren't speaking to each other. The story does have a happy ending though.
