The defences can be either passive, in that they attempt to stop an attack being successful, or
active in that they are designed to prevent an
assailant from even initiating an attack.
From its starkly arresting beginning, in which an act of violence is perpetrated against a housewife while her young daughter looks on, only for the daughter to become an
active participant in the revenge taken on the
assailant once Dad comes home, the film plots a highly original, beautifully shot course through a genre that often feels overgrown with familiarity.
