Snoopy goes to the library, and finds a book on magic. He decides to put on a magic show for the neighborhood children, calling himself "The Great Houndini," and using Sally Brown, Marcie and Woodstock as his assistants. Most of Snoopy's tricks have slight flaws to them, but his disappearing trick causes Charlie Brown to become completely invisible. However, before he can be changed back, a rain storm causes everyone to scatter.
Charlie Brown returns home, where he decides to leave, declaring himself 'doomed to roam the Earth as a lost soul.' Sally then wastes no time in moving her things into his room. However, being responsible, Charlie Brown decides to feed Snoopy one more time. Confronted by his invisible owner, Snoopy is coaxed to try and make Charlie Brown visible again. However, treatments from water, coating in clay, and wearing a sheet prove useless.
Shortly thereafter, Charlie Brown roams around the neighborhood, and finds Lucy in a clearing holding a football. Being invisible, he manages to sneak up on her and kick the football. Having the upperhand against Lucy's taunts, he then teases her with the ball, before forcing her to hold it in place, causing him to kick it. His triumphant laughter irritates Lucy.
Furious, Lucy goes to Snoopy and demands he make Charlie Brown visible again, promising to slug Snoopy if he does not. After studying the book, Snoopy experiments on Woodstock, causing parts of him to grow and shrink, before finally perfecting the cure to invisibility. Snoopy then hops off his doghouse, and goes searching for Charlie Brown, sending his de-invisibility powers hither and tither, hoping they will cure him.
Eventually Snoopy comes within range of Charlie Brown, and brings him back to the world of visibility. However, Charlie Brown is oblivious to this, and his attempts this time to kick the football are foiled by Lucy.
Even though he falls flat on his back, Charlie Brown still reveals in the fact that he had previously kicked the football. Lucy scoffs at this, saying no one will believe him. When Charlie Brown suggests that Snoopy will believe him, Lucy throws an insult to Snoopy as well. Angrily, Snoopy causes Lucy to levitate into the air. Charlie Brown and Snoopy leave Lucy hanging it midair. Sometime later, Linus comes by, and uses his blanket to get her down.
