A 25th anniversary tribute to the "Peanuts" comic strip.

A motorcross, a race of motorbikes through a series of obstacles, provides the occasion for Charlie Brown's latest attempt to win at something. He selects Linus as his pit crew and goes to a store to select a bike, and due to insufficient funds, he must settle for a tiny, run-down putt-putt. The majority of Charlie's opponents are eliminated in the race, and Charlie, wearing a makeshift helmet carved from a pumpkin, finds himself in close competition with his friend, tomboy Peppermint Patty, and the Masked Marvel (a.k.a. Snoopy, Charlie's dog).

Charlie Brown's team is forced to play against Peppermint Patty's in their field that has been converted into a lush garden.

The Peanuts gang, including Snoopy and Woodstock, have gone off to summer camp. After a few days of the usual activities, they all participate in a river-rafting race. Battling treacherous rapids, wild animals and cheating bullies from a rival tent, the teams make their way downriver to the finish line.

What a Nightmare, Charlie Brown! is the 17th primetime animated TV specials based upon the popular comic strip Peanuts, created by Charles M. Schulz. The plot is similar to that of Jack London's Call of the Wild.
