Unman, Wittering and Zigo are on the roster at Chantry, a British school for teenage boys, which looks down treacherously on ocean-splashed rocks. The three are students, but Zigo is constantly marked absent, for reasons unexplained.
Unman, Wittering and the rest of the class are present and they make for a sinister lot, blatantly threatening their new teacher, David Hemmings, with the same kind of death-on-the-rocks that has befallen his predecessor, unless he eases up on the scholastic schedule and runs their bets with the local bookmaker. The viewer may be both intrigued and puzzled, for while film is a compelling piece of dramatics about innocent-looking terrorists, it asks a great deal of credence.
Director John Mackenzie, working with a screenplay by Simon Raven, which in turn was fashioned from a television show by Giles Cooper, has in large part captured the viciousness. But why these youths are this way goes unexplained.
