Hey Arnold! The Movie

Life in the big city can be lonely. Luckily, Arnold and his pals live in a neighborhood so close-knit it could pass for a small town plopped down in the middle of a major metropolis. But when a powerful developer wants to knock down all the stores and house so he can build a mammoth "mall-plex," it looks like Arnold's neighborhood may be history. With the help of a sassy superhero and a mysterious deep-voiced stranger, Arnold and Gerald cook up a scheme to save their beloved blocks before it's too late. Can they find the crucial document before the bulldozers roll?
