The ZBZ girls throw a crazy competition among themselves as they each coach a different fraternity in a series of games. Casey coaches the Lambda Sigs and ends up developing a crush on one of the fraternity brothers. Meanwhile Rebecca tries to coach the Kappa Tau's and, at the sometime tests her relationship with Cappie.
The parents visit the campus for Freshman Parents Weekend. Rusty tries to hide something from his parents but Casey wants him to come clean in an attempt to get their parents off her case. Everyone takes care of Senator Logan while his daughter tries to have him hate Cappie. Dale seems to be the only one who is happy to see his friendly parents.
When the ZBZ girls express their desire to reunite with the Omega Chi's, Casey is put in a position of having to face her past relationship with Evan head on, causing her to come to grips with her feelings about him. Meanwhile, Rusty has a new crush and oddly enough it is Dale who helps him get a date with the girl. However, since Rusty has only had one relationship in the past, his eagerness to find someone new just might backfire.
Kappa Tau and Omega Chi face off in an epic battle of practical jokes complete with waterguns, duct tape and farm animals. Rusty tries to mediate the situation to save his friendship with Calvin but finds it only escalates the rivalry. Meanwhile, Casey learns that the only way to rid ZBZ of Lizzi, the conservative national rep overseeing them, is to forgive Frannie and reinstate her in a "diamond" ceremony.
When a scandalous story in the college newspaper hits stands trashing the Greek system, the brothers and sisters of Omega Chia, Zeta Beta Zeta and even Kappa Tau are in a frenzy to figure out who the undercover culprit could be. Meanwhile, after navigating some troubled waters with her boyfriend, Ashleigh turns to Calvin for support and even goes so far as to hit on him, only to learn he has a secret.
Allies become enemies when both Casey and Frannie are nominated for the title of Omega Chi Sweetheart. Who will prevail in this the ultimate cat fight? Meanwhile, as Rusty's relationship with Jen K. heats up, he longs for more private time with her but his judgmental roommate Dale is always around, making it difficult for the two lovebirds to spend time alone.
Couples are coming together. Couples are splitting apart. There’s Casey and Ashleigh—best friends and sorority sisters since freshman year, now they’re on the outs. Lack of support—Casey for Ashleigh—is the issue. But someone’s waiting in the wings to show Ashleigh she can be a friend, and that someone is Rebecca.
As mid-term week approaches, the pressure is building for Rusty as he is determined to maintain his grades while keeping up his social life at the fraternity. Of course, Cappie has the answers for him but is it the right thing to do? Cappie not only presents Rusty with an appealing offer of help but when he is partnered with Casey on a school project, Casey is tempted once again by her past.
In Casey's bid to become president of Zeta Beta Zeta, she tries to win over her sorority pledges by throwing a slumber party that turns scary when the lights go out. Meanwhile, the same stormy night at Cyprus Rhodes University brings trouble for Cappie when he gets an unexpected visit from a beautiful and mysterious girl named Destiny.
Cappie turns to Rusty for his brain power when the volcano for Kappa Tau's legendary Mt. Vesuvius party fails to erupt. Meanwhile, Casey and Evan are back on track as he introduces her to his powerful parents over dinner. But an unexpected appearance by Rebecca, a Senator's daughter, instantly bonds her to Evan's parents, leaving Casey to feel like an outsider with this blue-blood clan.
Everyone is asked to suit up and pick sides as Kappa Tau and Omega Chi go head to head in floor hockey. But that’s not as easy as it looks. Casey is rooting for Evan and Omega Chi, naturally. So much so that she sets Cappie up for a fall. But did she do it to help her man or to get back at Rebecca? Because Casey and Rebecca may be “sisters” but they sure don’t play like a team. When Rebecca learns that Casey of “Casey and Evan” was formerly with Cappie, she uses the info to backstab Casey and get herself promoted to ZBZ’s head of Athletic Support. That’s when Casey shows what she’s made of—no one is going to beat her.
It's the first week of school and the first week of rush and neither is going particularly well for Rusty. On his very first night trying to become one with his pledge brothers, he fell asleep on the job. His "brothers" let him know they weren't too happy by leaving Rusty to dash off to class sans shoes, with blue feet and covered in mud. Rusty's professor was not amused.
