Play It Again, Charlie Brown is the seventh prime-time animated TV special based upon the popular comic strip Peanuts, by Charles M. Schulz. This non-holiday Peanuts special centers on Lucy, her infatuation with Schroeder, and her willingness to do anything to win his affections.

School is out for the summer and Charlie Brown, Linus, Schroeder and Pig Pen are planning to spend it reading every comic book, watching television, practicing ballplay, and classical music, and having clean thoughts. However, Lucy tells them that she signed them up for camp. The girls are eager to go, but the boys hate the idea.(Linus adding that its like finding out that he was drafted.) The boys shove each other to get on the bus, while the girls line up in order. At camp, Charlie Brown is chosen captain of the boys camp. The boys and girls have a swim race which the girls win easily. Then they have a softball game, which the boys lose with only one run. Other competitions are just as lopsided. Afterwards, the boys sit around the campfire and reflect on how miserable they are. In one scene, the colors of the shirts of Schroder and Linus are mixed up during this scene.

Turkey, cranberries, pumpkin pie... and the Peanuts gang to share them with. This is going to be the greatest Thanksgiving ever! The fun begins when Peppermint Patty invites herself and her pals to Charlie Brown's house for a REALLY big turkey party. Good grief! All our hero can cook is cold cereal and maybe toast. Is Charlie Brown doomed? Not when Linus, Snoopy and Woodstock chip in to save the (Thanksgiving) Day. With such good friends, Charlie Brown - and all of us - have so many reasons to be thankful.

Poor Charlie Brown. He can't fly a kite, and he always loses in baseball. Having his faults projected onto a screen by Lucy doesn't help him much either. Against the sage advice and taunting of the girls in his class, he volunteers for the class spelling bee...and wins!

When Snoopy receives a letter from his original owner Lila, he goes to visit her in the hospital while Charlie Brown and the gang are on the lookout for him. Suddenly, Snoopy feels that he must go live with Lila, but must say goodbye to all his friends. In his adventure to the hospital, he encounters numerous "No Dogs Allowed" signs, an annoying little girl who desires to keep him, and more!

Most of the Peanuts gang is having trouble at school, but none more than Charlie Brown. In fact, he is told that he needs an "A" on a field trip report on an art museum or he will fail his grade. Unfortunately, Peppermint Patty, over-tired by Marcie waking her up at 4:00 in the morning, inadvertently distracts Charlie Brown and his sister from their group and they all mistake a neighbouring supermarket for the Art Museum. Even as they try to understand why all the displays are for sale so cheaply, Patty's weariness and her own ambivalent feelings about Chuck causes her to blurt out some hurtful comments about him. Now, Charlie Brown is going to have to realize his basic mistake in his report, while Marcie and Peppermint Patty search for a way of making amends to the boy they both secretly like in their own way.
