Lucinda temporally loses interest in Brandon when she flirts with Dylan to ask him to finance her documentary film. Meanwhile, Kelly and Brandon spend the weekend together at a task force retreat where they meet the university Chancellor, Milton Arnold, Dean Trimble and the Chancellor's teenage daughter Clare, where Brandon and Kelly become more attracted to each other and brush off Josh who's still hounding them. Brenda and Donna befriend a stray dog that escapes from the university's lab, whom they name Rocky. Also, Andrea discovers that Steve is allowing Muntz and his frat buddies to use her dorm room for nooners. Andrea protests, but changes her mind when Steve begins to date her dorm resident advisor, Kathy Fisher.

Brenda and Donna attend an animal rights rally, and are crestfallen when the university refuses to suspend animal testing. After Rocky dies of cancer, Brenda becomes involved with a small group of radicals. She serves as lookout when the group breaks into the university research building and tries in vain to save Andrea's lab (which does not harm animals in its testing). Brenda is arrested. Kelly and Brandon are furious when Dylan refuses to fund Lucinda's film. He finally tells Kelly that Lucinda came on to him. Brandon breaks up with Lucinda and Kelly confesses her kiss with Brandon. Dylan races over to the Walsh house to fight Brandon, but the tension is defused when he accidentally punches Steve.
