St. David's School for Boys is holding its first ever disco, and the girls from the local school are invited too! Matthew Evans and his friends think it'll be lame—especially Matthew, who can't dance to save his life. But when the boys learn that none of the girls want to come, and that the disco will have to be cancelled, Matthew wants to know why. Does St. David's have a bad reputation they don't know about? Do the girls really think they're that bad? Soon it becomes a matter of honor for Matthew's gang to save the disco from cancellation and make it a success.
