School of the Damned

A new teacher, Mr. Middleton, transfers to a British village school, where he's initially perplexed by the students' impeccable behavior. However, he soon discovers that a small group of students with special needs, who receive medication from an unknown source, are the ones responsible for maintaining order. These exceptional children, linked by a hive mind, exact deadly revenge on those who misbehave, leading Mr. Middleton to uncover a sinister government experiment and a dark conspiracy.
