Becky and Mark return home for Dan's high school football team's 20th anniversary party. It soon becomes apparent that there's trouble in paradise, so Roseanne schemes to break them up.

Leon convinces Jackie and Nancy to open the restaurant for breakfast, causing Roseanne to fear he is planning to force her out. Roseanne's car is stolen -- by DJ, and her violent reaction frightens her that she may repeat the pattern of her own abuse as a child, while Dan blames her anger on work stress.
