The eighth season picks up with Kitty and Red discovering their empty nest isn't very empty, even with Eric in Africa. Meanwhile, Hyde returns from Las Vegas, where he went to clear his mind after catching Jackie and Kelso in a compromising position. But when Kelso and Donna tell Jackie that Hyde planned on proposing to her, Jackie tries to win him back, only to discover that what happens in Vegas, doesn't necessarily stay in Vegas.
