Eric and his best friend, Jason, plan a summer trip to Europe. However, Eric's father, Alan, receives a notice from Mr. Feeny stating that Eric is failing European History. Alan gives Eric an ultimatum: he must achieve a B average on his upcoming tests, or he will be sent to summer school instead of Europe. When Eric and Jason ask Mr. Feeny for a grade leniency, Feeny refuses but recommends a history tutor named Tori Hart, who is also his highly attractive teaching assistant, then offers to help him cheat because she finds him attractive; During their initial tutoring session, Tori assigns Jason a massive textbook to read, but invites Eric to a separate, more personal study session. She quickly reveals that she finds Eric highly attractive and offers to simply give him all the answers to the test. Overwhelmed by guilt but desperate to pass, Eric writes down the answers but ultimately confesses the cheating to Mr. Feeny. While Eric initially shields Tori's identity and laments that he is just an average student, Feeny delivers a stern lecture, pushing Eric to realize his academic potential and refuse the easy way out. Meanwhile, Cory is absent from school due to an illness. When Topanga visits the Matthews house to deliver his homework, Cory reveals he has contracted mononucleosis.
