Valentine and Casper investigate when a teacher is assaulted by one of her pupils. In interview, the boy claims that the assault was in self-defence and that the teacher attacked him first. Valentine is convinced that the story is false, but it's Casper who manages to win the boy's trust to coax him into telling the truth. Meanwhile, Kent and Murphy attend the scene of a racially motivated arson attack on an elderly Jewish man. Initially suspecting that the case may be related to the Asian unrest in the area, Perkins later discovers that a dispute with a property developer may have been the catalyst in an attempt to get the man, who is the last sitting tenant, to move out of the property.
