Hyde meets his half-sister, Angie, with whom he does not see eye to eye. Eric conceals his love of roller disco from the gang.

When an upset Kitty discovers the kids have their own plans for Thanksgiving, Red guilts Eric into giving up via Styx tickets to stay home for the holiday.

Hyde is upset when he discovers his new sister Angie has started dating Kelso; Donna agrees to help out Red's falling Business by plugging it on the radio.

Jackie constructs an elaborate hoax about being engaged to Fez after meeting a woman with the perfect life; Donna and Eric conspire to ruin Kelso's romance.

Kelso enjoys rubbing in Hyde's face that he's doing his sister. Donna is jealous her new, music-ignorant radio station assistant 'Sizzling Sarah' is a sex symbol far sooner then she got a nickname, yet refuses to promote on a billboard in bikini a Tom Jones signing session, most popular with the local females. When Sarah offers to do it, station manager Stan fires Donna. Jackie and Hyde want each-other back but don't dare tell so, except she to Fez, who has an even hotter dream. Eric thinks up a nasty revenge. Kitty was too emotional to go for an autograph and delegate Red too impatient, so he fakes it, but the star is held back and Bob went too.

Angie proves it's possibly to be worse at mastering the art of 'burns' then her lover Kelso at anything intellectual. After another ass-aimed lecture from Red about wasting an entire year, Eric hits on great with fellow comics- and SciFi-erudite unemployed coach potato Stew Bailey, but is turned off seeing Stewie's ma is his best friend at age 36. Jackie has her TV 'news' show with Donna behind the camera, who get her freaky nervous just before it goes on air, so it all goes horribly wrong. After a pep-talk from fellow screw-up Eric she tries again, guest-starring 'slut expert' Michael, who also stars unexpectedly as the perfect good sport when Angie tries again.

Kelso chooses godparents for daughter Betsy; someone keeps breaking in to the record store.

Michael has decided it's time to dump Angie, but doesn't know how to do it less insensitively then the many other times he dumped girls, so he chickens out. He could have spared himself the trouble: she dumps him because her dad has decided to promote her to manager of his Milwaukee record shop, although she hasn't learned anything about the business, so Hyde is not happy - or didn't she get that right? Eric finally has the paperwork ready to study, but now Red announces his college fund is now lost on the muffler shop, and student counselor Mr. Bray is only interested in girls, especially Donna. When he finally finds a solution, it comes at the price of a year further away then either Kitty or Donna could accept.
