Sam loves his home and social life but hates his new teacher, Ms Brown. She enjoys humiliating Sam and his friends (or, at least, he believes she does). After a classroom incident, Sam's best friend, Angie, decides to take matters into her own hands. Angie knows it won't be easy for her to get Ms Brown fired, but, whatever it takes, she's determined to make it happen. Even if it means lying to adults, deceiving parents, bullying friends and stealing money from a charity. Sam has to reconcile his desire for Ms Brown's downfall with his conscience as Angie hatches, reveals and executes her ruthless plan.
