High school honor student Jodi Melville (Amy Adams) is convinced that her classmates dislike her because she is overweight. In her efforts to reduce, Jodi vows to subsist on a diet consisting only of the vegetables growing in her parents' greenhouse. Alas, those vegetables have been infected with kryptonite, and before long Jodi has developed jaws like iron -- and an insatiable craving for "live" meat. This could spell disaster for Clark's (Tom Welling) best friend Pete (Sam Jones III) who has developed a crush on Jodi. ~ Hal Erickson, Rovi
