Das große Abschiedsfest für Pollyanna ist gekommen. Pollyanna hat all die Kinder aus Jamies Haus eingeladen, was Tante Carew überhaupt nicht passt. Sie befürchtet, dass die vielen lärmenden Kinder die anderen Gäste stören könnten. Die kleine Sadie, das eingebildete Mädchen aus Tante Carews Nachbarschaft, will denn auch die Feier verlassen, weil Pollyanna seit dem Eintreffen der ärmlich gekleideten Kinder keine Zeit mehr für sie hat, aber dann kommt sie mit Jamie ins Gespräch und freundet sich schnell mit dem sensiblen Jungen an. Zusammen bittet sie mit Pollyanna Tante Carew, dass sie Jamie auf der geplanten Stadtrundfahrt im Auto mitnehmen. Tante Carew ist zunächst empört darüber, da sie die Stadtrundfahrt eigentlich nur für Pollyanna geplant hatte, aber ihr bleibt wieder einmal nichts anderes übrig als nachzugeben.
Pollyanna is in seventh heaven to learn of the farewell party that Ruth has decided to host complete with encouragement to invite everybody with which she is acquainted; in a bid to clear up the ambiguity that the happy-go-lucky little girl reads as a license to invite anybody she wants, Ruth discusses her plans with Pollyanna but capitulates upon all of her arguments have been nullified and upon Mary announcing that Polly has come to pay a visit. Even with the aunt-niece sentimental reunion, Pollyanna cannot shake the anguish and frustration that she could not successfully locate Jamie Kent in the limited time she has before returning home to which Polly is not slow in explaining that such is a very difficult enterprise that she herself would not be able to do and that the farewell party is a sign of the gargantuan metamorphosis Ruth has undergone; after advising Pollyanna that keeping her spirits up will go a long way toward a mutual epilogue of euphoric memories, Polly goes to meet with Ruth where the two women compare notes about their lives before and after Pollyanna. The farewell party starts out well enough with Pollyanna and Sadie reconciling their differences about how they behaved toward each other when Chipmunk went missing before Ruth pipes up to suggest that Sadie accompany Pollyanna on the sightseeing tour around Boston after the party; no sooner does Sadie happily agree to this before something unexpected happens much to Ruth's astonishment and Pollyanna's delight: James and Mickey arriving on the scene to partake of the party . . . in convoy with all the other children from Murphy's Alley!!! Mickey is not slow in leading the other kids through rendering unto Ruth their gratitude for the renovated building first through a comical introductory speech and then through a dance sequence before the ecstatic crowd at which Pollyanna is only too happy to join in while James intercepts Sadie as she is storming away in disgust into a diatribe of behind-the-sce
