Sam is small, blond and wild - with a giant attitude problem - and he immediately starts to wreak havoc on Matthew's social life. Desperate to get their own back, Matthew and his best friends cook up a brilliant, outrageous plot that will bring Sam down a peg or two AND deal a stunning blow to the bitchiest girls at school.
Victory is theirs. Until Operation Sam runs hysterically out of control.
