Kelly (Jennie Garth) and Silver (Jessica Stroup) are surprised when Donna (guest star Tori Spelling) shows up at their door, straight off a plane from Japan. Annie (Shenae Grimes) and Dixon (Tristan Wilds) decide to spend their spring break on a road trip to visit someone from Dixon's past, while Ethan (Dustin Milligan) decides to step out of his bubble and volunteer with Habitat for Humanity. Naomi (AnnaLynne McCord) joins the Habitat build after learning that Liam (Matt Lanter) is also attending, but is clearly out of her comfort zone. While Kelly and Donna are dining on sushi, Diablo Cody (guest starring as herself) convinces Donna to design a dress for her for a red carpet event.
