(December 2015) (Learn how and when to remove this template message) Richard "Richie" Rich Jr. (Macaulay Culkin) is the world's wealthiest kid, the son of billionaire businessman and philanthropist Richard Rich, Sr. (Edward Herrmann). Richie has been raised with the best of everything money can buy, but with only his loyal butler Herbert Cadbury (Jonathan Hyde) as a companion, he lacks any friends his own age. But he thinks he might get his chance at a dedication to the reopening of United Tool, a factory Richard recently acquired (intending to modernize the factory and give it away to the workers as a token of goodwill). There Richie encounters a group of sandlot kids playing baseball. Unfortunately, before he is able to talk to them, the too-strict head of security, Ferguson (Chelcie Ross), stops Richie and sharply pulls him away. Richard tries to keep in touch with Richie and spend time with his son whenever he can. He even had the Rich family's head scientist, Professor Keenbean (Mike McShane), invent a machine called the "Dadlink" that pinpoints Richard's location in seconds, so Richie can talk to his dad whenever he's away on business. Meanwhile, the greedy CFO of Rich Industries, Laurence Van Dough (John Larroquette), is planning to steal the Rich financial fortune, believed to be stored in the Rich family vault. Van Dough, with the help of Ferguson, plots to blow up the plane carrying the Rich family to England. Cadbury, seeing Richie's loneliness, makes a suggestion to Richie's mother, Regina (Christine Ebersole), and arranges for Richie to stay home in Chicago with the sandlot kids for a weekend of fun. That weekend allows Richie to earn the friendship of the sandlot kids, most importantly, Gloria Pazinski. Cadbury also begins to fall for Gloria's mother, Dianne, who is rather plain-looking but very warm-hearted, and with a caring, outspoken nature...
