It's been 30 years and with rising temperatures melting icy mountain tops the previously frozen Willoughbys have thawed out and are about to return!

Although they grew up as wretched orphans, the Willoughby siblings also became heirs to the the Melanoff candy company fortune. Everything has turned out just splendidly, except for one problem: Richie Willoughby, son of Timothy Willoughby, is an only child and is quite lonely.

Winifred and Winston Poore have long admired the toys of their neighbor Richie Willoughby and finally befriend the mysterious boy next door. But just as Richie finally begins to make friends, selling sweets is made illegal, and the family's fortune is put in jeopardy. To make matters worse, Richie's horrible Willoughby grandparents—frozen atop a Swiss mountain thirty years ago—have thawed, remain in perfect health, and are making their way home again.

What is the point of being the reclusive son of a billionaire when your father is no longer a billionaire? What is the future without candy in it? And is there any escaping the odiousness of the Willoughbys?
