Courtney Thorne-Smith, Mariska Hargitay, and Jo Ann Willette are a trio of teeners who've just graduated from high school and are heading off to the school of hard knocks (and knockers!) in Welcome to 18 (1986). When their plan to work at a Nevada dude ranch doesn't work out, they land in Lake Tahoe with a new bud, Cristen Kauffman, whose boyfriend, E. Erich Anderson, says he can get them work. Unfortunately for the comely three, Cristen's squeeze is kind of a sleaze, and the petty criminal gets them in trouble with a bad-news job at a casino. It's not long before the toothsome threesome is in trouble . . . and the trouble's about to get even worse!
