Reuben books the Partridges in what they all believe to be a mountain resort called Rose Mansion. At the family's first performance, they realize that there is only one person seated in the audience, named Sidney Rose. A multimillionaire who has become a recluse for the sake of privacy, Sidney must bring all entertainment to his own estate. On the rare occasions that he does go out, he does so in disguise. The lonely man develops an affection for the Partridge family and tries to persuade them to stay at Rose Mansion for a few weeks, but they are unable to do this and so invite him to come to their house. Sidney says he is afraid of crowds that would attack him if he did this, thus politely refusing the invitation. A few days later, a policeman comes to the door, who turns out to be Sidney, planning to spend a few days with the family. Unfortunately, a news reporter comes in for an interview, and although Sidney is now disguised as a TV repairman, the reporter recognizes the millionaire and broadcasts his presence on TV. To everyone's surprise, mobs of people do not immediately gather at the Partridges' doorstep, and in fact, Sidney is rather crushed by the lack of response. But by now, he is ready to come out of seclusion in order to lead a normal life.
