School is ending for the summer, and the stick figures on the school crossing sign are jealous of all the vacation plans they hear the students making. The stick figures work hard--maybe they deserve a vacation, too! So they abandon their signpost and set off on an adventure, inviting along all the other underappreciated road signs they meet on the way. It's all fun and games for a while, especially when they stumble upon a fantastic amusement park. But the people they've left behind are feeling their absence, and soon there are traffic tangles and lost pedestrians everywhere. The signs are more important than they realized, and now it's time for them to save the day!
