17 - 20: Regarding Margie

After a spring-cleaning frenzy and inhaling too many fumes, Marge suffers from retrograde amnesia. In an effort to bring back her memory, Homer takes her around town to re-familiarize her with her surroundings. Marge still has no recollection of who Homer is and puts herself back on the singles market. Not until she realizes that Homer is truly genuine at heart will she remember who he is and why she loves him. Blackboard ' I will not leak the plot of the movie'.
