Madame Pernelle, visiting her son Orgon's home, adamantly praises Tartuffe's apparent virtue, despite objections from others who see through the hypocritical facade. Orgon, enamored with Tartuffe, is more concerned about him than his wife's illness or his daughter Mariane's marriage. Damis, Orgon's son, tries to expose Tartuffe but is disowned. Orgon, blinded by admiration, plans to make Tartuffe his heir, leading to a series of events revealing Tartuffe's true deceit. With the intervention of Elmire, Orgon's wife, and the king's recognition of Tartuffe's fraudulence, the family is saved from eviction, and Orgon's property is restored. Madame Pernelle, initially steadfast in her support, is ultimately convinced of Tartuffe's treachery, highlighting the play's themes of deception and misplaced trust.
