After James Henry Trotter's parents are tragically eaten by a rhinoceros, he goes to live with his two horrible aunts, Spiker and Sponge. Life there is no fun, until James accidentally drops some magic crystals by the old peach tree and strange things start to happen. The peach at the top of the tree begins to grow, and before long it's as big as a house. Inside, James meets a bunch of over-sized friends--Grasshopper, Centipede, Ladybug, and more. With a snip of the stem, the peach starts rolling away, and the great adventure begins!
