The last semester of senior year, Kyle and Wendy get pretty close. Maybe too close, since she's dating his best friend.

Feeling abandoned by his best friend, Kyle ends up spending time with a certain poor kid that no one has seen in a while.

Stan is back in South Park after college, and a lot has changed. All he wants to do is get out of the town and never look back.

It's the last party before they all leave for college or to start their new lives. The whole grade will be there, and everyone has something going on.
