Peter Rabbit, his mother, and his three sisters live under a fir tree in a big forest. One day, Mrs. Rabbit leaves her bunnies to go through the woods to the baker's house. She cautions them not to go to Mr. McGregor's garden while she's gone, but Peter immediately disobeys her. He has a good time at first, but he eats so much it makes him feel sick. Then, when he goes to look for parsley to soothe his stomach, Mr. McGregor spots him!
