A crossbreeding of two genres, thriller and teen comedy, yields two mediocre movies for the price of one. A stockbroker (Jon Cryer) called as witness in a criminal case narrowly escapes death, and hides out incognito as a small-town high school student (thriller); his nerdy high school cousin (Keith Coogan) helps him out, and has various misadventures trying to get a driver’s license (teen comedy). Annabeth Gish plays the hero’s girlfriend; Bob Giraldi directed, after a fashion. (JR)
