A banner for the winter dance, The SnO.C., is raised as the show begins. Ryan asks Lindsay to go with him, but she says that the two should remain friends. During lunch, meanwhile, Marissa and DJ head back for a make out session. However, it is interrupted by Julie, who scolds Marissa and fires DJ.
Seth goes over to The Bait Shop to ask Alex to the dance, but she claims that it was just a meaningless kiss on Saturday night. In response to Lindsay's diss and Marissa's shame over DJ, Ryan and Marissa decide to go to the dance as friends. In adult news, Sandy has still not heard from Caleb. He tracks down Renee Wheeler, but she won't reveal anything.
Lindsay, being a crazy girl, then tells Ryan that she does wish to be his date, but he has already made the plans with Marissa. Zack sees Seth and Summer chatting, so he cancels their dance date, while Seth quits his job at the bar in order to play along with Alex's games. Once the dance begins, DJ shows up and Marissa brings him into the dance. Julie sees this and is about to tear them apart until Jimmy intercedes. He and his ex-wife kiss. Zack, meanwhile, enters the dance and sees Summer dancing with Seth.
Ryan leaves the dance and heads over to Lindsay's house. He says that he likes her and will not give up pursuit. Back at the Cohen's, Caleb admit that he had an affair with Renee and has been paying her for the last 16 years because they had a child together. After speaking with Alex at The Bait Shop, Zack decides to go back and fight for Summer. He does, literally, by punching out Seth. Alex, however, followed along and comes to take care of Seth. The two of them kiss back at the bar and Zack and Summer leave the dance as a couple. Changing her mind yet again, Lindsay goes into the pool house and makes out with Ryan. During this time, Renne stops by to chat with Sandy. She sees Lindsay and the young red head responds with, "Mom, what are you doing here?" Cut to black.
