 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.
