Fern gets a pig that her father was going to kill. She named it wilbur and she kept it in the house until wilbur moved to her uncles barn.
Wilbur now lives in the barn. He meets a spider and she promises Wilbur he wont be killed. He doesn't believe her until he wakes up and sees her web says "SOME PIG". Everyone in the town gets crazy and thinks the pig is a miracle. Wilbur thinks hes not going to be killed now.
Wilbur goes to the town fair. The spider (Charlotte) is going to be having her kids so she doesnt want to go but she goes anyways. She also sees a pig who is much bigger than wilbur so wilbur thinks hes going to lose and be killed. But charlotte makes a web that says "HUMBLE" so he thinks hes going to win and not be killed now.
Wilbur gets first place in the fair. He then has to carry the spiders eggs back to the barn because Charlotte is to weak to move. Wilbur gets back and Charlotte dies. He then waits months and months for the spiders to hatch.
Spring time comes around and the eggs hatch. All of the spiders grow up and leave. Only three stay. Them and wilbur become friends and then those spiders have kids. Then those spiders have kids for years and years. Wilbur lives his peaceful life until he dies of age.
