As season six of
That '70s Show gets under way, Red Forman (
Kurtwood Smith) is recovering from a heart attack, a state of affairs that has put a severe strain on his marriage to wife Kitty (
Debra Jo Rupp). Meanwhile, Kitty and Red's son, Eric (
Topher Grace), temporarily shelving plans to attend the University of Wisconsin, has asked "girl next door" Donna Pinciotti (
Laura Prepon) to become his bride, even as Donna's divorced dad, Bob (Don Stark), terminates his relationship with his lady friend Joanne (it had been originally plan for Bob and Joanne to wed as well, but this plot development was dropped when the actress playing Joanne, Mo Gaffney, signed on to another series). Also, exchange student Fez (
Wilmer Valderrama) has narrowly avoided deportation via a quickie marriage to Eric's sister, Laurie (who is now being played by
Christina Moore). And in other events, Eric's pal Kelso (
Ashton Kutcher) has entered the Police Academy, though his future career may be hampered by the fact that he has impregnated his current girlfriend, Brooke (
Shannon Elizabeth); Kelso's former girlfriend Jackie (
Mila Kunis) is not so sure about her present relationship with the moody Hyde (
Danny Masterson); and
Brooke Shields makes her first appearance as Jackie's mother, Pam, who has an implied "topless" scene halfway through the year. As the season draws to a close, the wedding of Donna and Eric may not come off due to an unforeseen development -- namely, the disappearance of the groom -- and Hyde is shocked to discover the identity of his real father. ~ All Movie Guide
