The gang plan to go to a disco in Kenosha. Kitty teaches Hyde how to dance, and Bob mistakenly thinks they are having an affair. Jackie dances with Fez and Hyde with Donna, leaving Eric and Kelso slightly jealous.
When the gang hears there is a disco in Kenosha they decide all to go. Hyde doesn't want to go at first because he hates disco and can't dance. But when Donna says she would love to go he takes dancing lessons from Kitty. Bob walks in on Kitty and Hyde dancing and thinks they are having an affair. He tells Midge about it but they don't know what to do. Midge tries to confront Kitty about it but it only makes Kitty think that Midge is having an affair. Bob tells Red about it who at first wants to kill Hyde but then they realize Kitty was teaching Hyde to dance.
Once the gang is at the disco, it is discovered that Kelso also cannot dance, so Jackie does not want to dance with him. She then dances with Fez who is an amazing dancer. This prompts Hyde to ask Donna to dance with him while Eric doesn't want to dance. During the dance Hyde tries to make a move on Donna which she rejects.
Meanwhile Fez and Jackie are outside talking, Fez tells Jackie she is the reason he is such a good dancer when Kelso storms out of the disco and threatens Fez that he has to stay away from his girlfriend. When they go home Eric and Donna dance and their relationship gets stronger. In the end credits Fez plays the tape of their circle to Kelso, Hyde and Eric. At the end of the tape he says "see you are all stupid".
