When her boyfriend, jock Billy Durden, dumps gossip queen Dawn Stiles, a day before the Smallville High prom, the bitch which everybody expects to become Prom Queen, regardless of Chloe being entered (behind her back) as 'alternative', decides to go with Clark (who intended to stay home) instead. But while driving on the road, she crashes her car near the mother-load of meteoric green kryptonite, which causes her spirit to leave her dying body and enter someone else's body by a mere touch, starting with Martha Kent driving on the road, then Lana, and so on. Clark and Chloe try to figure out what's happening. Meanwhile, the corpse of Bridgette Crosby, of whom no official record exists, is found in Lex Luthor's garden. Lex keeps Jason at arms length, who for once knows more about her mysterious death... and recovers the second Kryptonian stone in her possession.
