When Snoopy turns Charlie Brown invisible in a magic act, he has trouble changing him back.

As they begin their journey home from their student exchange term, Charlie Brown and the gang find themselves sidetracked. They have severe car trouble and more importantly, they pass by various monuments to World Wars I & II. With Linus guiding them through these memorials, they learn about the events of the wars and the sacrifices required of the troops who fought them.

This hour-long anthology presents six animated shorts. "Peanuts" creator Charles Schulz appears on camera to introduce these adaptations of some of his favorite strips, which include Charlie Brown spending two unexpectedly pleasant weeks at summer camp; Peppermint Patty and Marcie taking jobs as golf caddies, with disastrous results; and Lucy trying to cure Linus' dependence on his security blanket.

When the circus comes to town, Snoopy naturally pays a visit. There he falls for a beautiful poodle performing there. He soon runs away to join it. While he quickly becomes a star performer, Charlie Brown is distraught by Snoopy's decision while Snoopy himself has to face some realities of show business himself.

Introduced by creator Charles M. Schulz, this special follows the Peanuts gang through a series of individual comic strip adaptations, including Peppermint Patty accidentally attending a dog obedience school and Lucy trying to win Schroeder's heart by destroying his piano. Chaos peaks when Charlie Brown lands in the hospital with a mysterious illness, prompting a guilt-ridden Lucy to make a dramatic promise regarding her infamous football gag if he recovers.
