Two brothers move to a new town and soon fall in with the wrong crowd. Nothing unusual about that, except these particular no-mark punks also happen to be blood-swilling vampires. The older brother (Jason Patric) proves easy prey and is soon a fully paid-up member of the undead. But the younger brother (Corey Haim) is made of tougher stuff and, along with a couple of friends, decides to make a stand. Pretty soon the suburbs start swinging to the sound of teen-vampire combat.

Jo Harding (Helen Hunt) leads a team of scientists who are set to launch a contraption that can retrieve information from the eye of tornadoes. Bill (Bill Paxton), the inventor of the machine and Jo's ex-husband, arrives with his new fiancée Melissa just as a major storm is about to hit the area. Unable to resist the call of the wind, Bill rejoins his team in a dangerous chase after the mother of all tornadoes: the F5.
