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 (recurring guest star ERICA DURANCE) attends the prom, and Chloe attempts to set the school on fire. Lex gives the seniors a special gift by getting the band LIFEHOUSE (themselves) to perform at the dance.

The spirit of a young girl is released after Lois (recurring guest star ERICA DURANCE) finds a corpse in the walls of the Talon. Clark and Lois must follow the trail of the spirit and find her killer, who has been preying on girls in Smallville for the past 10 years. When Lois is suddenly kidnapped, Clark comes to the rescue.
