Michael (John Stockwell) and his girlfriend Ellie (Danielle von Zerneck) break into a military junkyard to find a science project for Michael’s class. They instead discover a strange glowing orb that absorbs electricity. When the orb begins to blend past, present, and future, it’s up to Michael and Ellie to stop the orb and save mankind.
Teen misfits Gary (Anthony Michael Hall) and Wyatt (Ilan Mitchell-Smith) design their ideal woman on a computer, and a freak electrical accident brings her to life in the form of the lovely, superhuman Lisa (Kelly LeBrock). She outfits Gary and Wyatt in cool clothes, surprises them with a Porsche and helps them stand up to jerks Ian (Robert Downey Jr.) and Max (Robert Rusler). But, all the while, the boys must hide Lisa’s existence from Chet (Bill Paxton), Wyatt’s nightmare of a big brother.
