A stunned Chloe is nominated for prom queen and tries to enlist her reluctant friends Clark and Lana to attend the dance with her. Chloe's rival for queen, Dawn Stiles (Beatrice Rosen), crashes her car into a ravine filled with Kryptonite. Dawn's spirit is released and enters the bodies of the others -- making them behave uncharacteristically. As a result, Lana asks Clark to be her prom date, Lois attends the prom, and Chloe attempts to set the school on fire. Lex gives the seniors a special gift by getting the band Lifehouse to perform at the dance.
