THE CRIME It all started when Will mooned the girls' school bus. It wasn't his finest moment. And it's the last time William Armstrong will sully the St. Andrew's community, says Principal Waddlehead-er, Waverton.THE PUNISHMENT That's when a teacher worried about Will's home situation comes up with an idea. Why not let Will, a talented guitarist, give back to the school in a progressive manner? Why not have him play in . . . THE SCHOOL MUSICAL?THE MUSICAL Now Will is stuck in the school production of The Boy Friend. He's a laughingstock, and he has to give up his weekends for a show set at a girls' finishing school.THE PLAYERS There's the trombone-playing seventh grader who proclaims himself Will's best friend and refuses to leave his side. Then there's the undeniably attractive leading lady. Although she might be in love with her costar, the new football hero (and dazzling singer!).Sharp-witted, funny, and poignant all at once, this is the story of a boy going through a difficult time who, in a most unlikely way, discovers the person he truly wants to be.
