The 2nd Movie:
The story takes place after the ending of the anime series and is about Syaoran and Sakura getting together, and how Meiling and Tomoyo plot to get S+S to become a couple! Also, there is a Clow Card who hasn't not be captured yet, and she's very angry that Sakura has sealed away all of her friends away... so she's out to get revenge...!!
Sorry, I haven't watched the movie yet, so I know only very little about it. But I do know that it's a very sweet movie, and is a must see for any S+S fan! ^_^
