Preparing for her father's monthly visit, Sabrina anticipates the teenage trauma of introducing her father to her boyfriend (actually, Edward and Harvey do reasonably well), but isn't prepared for the teenage trauma of meeting your divorced father's new girlfriend, an attractive supernatural lawyer named Gail. Initially hostile, Sabrina is persuaded by her aunts to see reason and tries to make amends by asking whether Edward and Gail plan to get married. When they simultaneously answer "Yes" (Gail) and "No" (Edward), Gail furiously dives into Sabrina's magic book.

Sabrina hits a really bad day: disregarding her aunts' warning, she buys a "tomorrow" ball from a supernatural traveling salesman, and believes its prediction that she will get an "A-" on her science project. Unfortunately, Mr. Pool (dressed in a kilt for "Scots Pride Day") doesn't share that estimation of her work, and gives her a C- and a chance to redo the project overnight. Instead, Sabrina tries to sneak out of the house aboard her trusty vacuum cleaner to attend a "Smashing Pumpkins" concert, but gets pulled over by a flying motorcycle cop and cited for flying over the town "with a full bag and bad dust emissions."
