A few months have passed since the events of last semester and the gang is just falling into the new rhythm of the spring semester. Two new RAs have joined the staff and Mitch has taken an internship up in Wisconsin with Rebecca Lane Inc. How are the new RAs fitting in with the rest of the staff and how is Mitch adjusting to life up north?

Mitch comes back to Champaign-Urbana because of an email he received from Monica asking him to return to campus for Valentine's Day. Meanwhile, Daniel and Henry take out Monica Edwards and Sandy on a double date and Steven attempts to find a wingman to go with him to visit the Girls Gone Crazy bus.

Katharine experiences her first night on duty while Christi plans a birthday surprise for Alexis. Meanwhile, Steven gets himself stuck in a sticky situation and we finally find out what happened between Mitch & Monica Burns on Valentine's day.

It's Unofficial St. Patrick's Day, the time of year when everyone at the U of I gets buck-wild! It's a time of green beer, crazy antics, and doing things that you hope to forget the next day, except for those who draw duty! Steven, Alexis, Monica, and Christi spend their day enjoying the alcoholic festivities while Daniel and Katharine are stuck inside dealing with the not so pretty messes left behind. Meanwhile, Henry and Sandy must work through a difficult time in their relationship.

As the end of the semester nears, the RAs of C.S.R. begin to plan an end of the year dance as everyone recovers from the events of Unofficial St. Patrick's day. Henry and Sandy are still having a rough time, and Alexis and Christi are a bit disturbed by the fact that they cannot remember the events of Unofficial.

As the staff of C.S.R. prepare for the end of the year semi-formal, an old enemy teams up with Janet and Anthony to stir up some trouble. Can Old Ben safe the day? And will Mitch make it to campus in time?
