Richie Rich is the world's poor little rich boy. He's the richest kid on Earth, but all he really wants are friends (well, he's got everything else). He spends his days living by a meticulous schedule that sometimes even includes filling in for his father at public appearances. His wealthy schoolmates are just as busy as he is and not quite as desperate to do "regular kid things" as Richie. While filling in for his father at a public event, however, Richie takes notice of some inner-city, street-wise kids playing baseball in a vacant lot nearby and makes an attempt to join in. They soon make it clear that he does not belong, and poor Richie goes home in despair. Seeing his disappointment, Richie's protective and caring butler, Cadbury, makes arrangements for the kids to come to the Rich family mansion and spend a day with the boy, much to Richie's joy and surprise! The gang of kids have a ball riding Richie's rollercoaster, trying out his kid-a-pult, and eating in his own, personal McDonald's. At the end of the day, Richie's new friends have accepted him as being just another regular kid, though they more than appreciate the benefits that come with his friendship. Still, feisty redhead Gloria, self-appointed leader of the bunch, makes it clear that they like Richie more for who he is than for all the neat stuff he has. Richie doesn't have much time to be happy about: that, though. Word soon arrives that Richie's parents, benign but sometimes clueless Richard and Regina Rich, were victims of an assassination attempt and are now lost at sea and assumed dead. As the Riches survive in a life raft on Perrier and champagne, Richie is forced to take over the family company and keep it safe from malicious top executive Lawrence Van Dough, who planned the attack on Richie's parents in the first place. Luckily, with his new friends' help, Richie turns out to be a business whiz! Richie has to become even more assertive when Cadburry is framed and locked up for the murder of Richie's parents though. Some help from in-house inventor Professor Keenbean allows Richie to break Cadburry out, but matters become even more complicated when the Rich parents finally are rescued by the villainous Van Dough and his cronies themselves, purely so they can open the voice-activated lock on the family vault in Mt. Richmore. Now, Richie and his crew must prove their mettle and save Richie's parents and fortune from a criminal desperate to do anything to have it all!
