That 70's Show revolves the lives of several 17-year-olds living in Point Place, Wisconsin, 1976. The head of the group is Eric Forman (Topher Grace) who lives under the authority of parents Red and Kitty (Kurtwood Smith & Debra Jo Rupp). Living next door is girlfriend Donna Pinciotti (Laura Prepon) and her parents Bob & Midge (Don Stark & Tanya Roberts). The rest of the gang includes Fez (Wilmer Valderrama), a foreign-exchange student who's soaking up American culture like a sponge, Jackie Burkhart (Mila Kunis), her on-again, off-again boyfriend Michael Kelso (Ashton Kutcher), and Steven Hyde (Danny Masterson), a conspiracy theorist who believes Xerox will take over the world. The gang usually spends their time in Eric's basement, thinking of their lives, parents, and futures, but they manage to get into funny adventures and mishaps along the way through their teenage lives.
