David's work and study schedule begins to take a toll on him when mid terms come around, leading him to start using crystal meth. His erratic behaviour worries Donna and Kelly. Dylan wants to help Suzanne with her financial troubles by giving her $10 000 but Jim urges Dylan to let him do a background check on her first. Steve decides to take his suspicions about John Sears to their fraternity chapter president. Brandon continues to tutor D'Shawn in sociology but still feels that Professor Randall is giving him preferential treatment. During a basketball game, D'Shawn sustains an injury that he fears will impact his future career prospects. Andrea learns from her new RA that Dan Rubin has transferred to another dormitory.

Donna tries to make up with David, whose increased drug use turns her away. David also steals $150 from his father to buy more amphetamines for himself. When his drug dealer is arrested later, he finds himself in possession of a huge stash of narcotics and calls on Dylan for help. Meanwhile, Jesse and Andrea meet with her grandmother to get her blessings before their wedding and reception at the Peach Pit. A dangerous affair begins between Brandon and Lucinda, who shows her true colors when she starts teaching her anthropology class of human sexuality and preaches the need for multiple partners, seeing sex as her personal weapon. Brenda gets a surprise visit from a long-absent Stuart on Valentine's Day.

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.

While working with Kelly to recruit guys for the "Men of CU" beefcake calendar that they're working on, Donna goes on a spontaneous date with D'Shawn just to make David jealous when she finds him flirting with his blind piano teacher Holly. Meanwhile, Steve sees no reason to keep the secret that their frat president, Mike Ryan, is gay despite being sworn to secrecy.
