After being mugged in the parking lot of the Deering Plaza after work, Kristy gets nervous about being out alone. Not only does she take a self-defense class with Mary Beth and Julie, but she arms herself with pepper spray. However, after leaving work early and not waiting to walk out of the mall with Julie and Michael, Kristy mistakenly thinks Michael is a mugger and attacks him with her pepper spray. Meanwhile, Rico, Silk, and Hammer all try to get Coach Katowinski to use his extra Pacers ticket on one of them.
