Quiet, kindhearted introvert Marcie has lots of brilliant ideas to help her friends achieve goals and solve problems. But when the world takes notice and the spotlight lands on her, sharing those ideas becomes a challenge.

Franklin is new to town and hoping to make friends, but his usual tactics don't work on the Peanuts gang. When the Soap Box Derby arrives, he's sure it's a chance to impress new pals and teams up with the only other unpartnered kid: Charlie Brown.

Music and glee fill the air as Charlie Brown and the gang head off to summer camp. First-timer Sally doesn't get what all the hype is about. But when the camp may be forced to close, they team up to save it so more kids can make their own special memories.
