|Plot: (from IMDb)|
Nerdy, reserved bookworm Needy (Amanda Seyfried) and arrogant, conceited cheerleader Jennifer (Megan Fox) are best friends, though they share little in common.
They share even less in common when Jennifer mysteriously gains an appetite for human blood after a disastrous fire at a local bar. As Needy's male classmates are steadily killed off in gruesome attacks, the young girl must uncover the truth behind her friend's transformation and find a way to stop the bloodthirsty rampage before it reaches her own boyfriend Chip.
Needy seems to have more than friendly feelings for Jennifer, so she doesn't object too much when Jennifer, one evening, begins to make out with her in her bedroom.
