There’s some confusion at Deansgate School as Pc’s Nate Roberts and Mel Ryder are called in to investigate a burglary in teacher Becky James’ classroom only to find nothing apparently stolen. Instead they find the suspects have left behind a huge painted canvas.

Nate finds out that one of the suspects is Kim whose father is a school governor. Kim admits to the crime saying that she and Jimmy did it for a dare. But Kim’s father is furious blaming the school and announcing he is taking his daughter elsewhere.

After the meeting, Nate is concerned that teacher Becky has not been in to work and goes to her house with Mel. There, the pair find the teacher badly beaten and unconscious on the kitchen floor. Who attacked Becky? And what do they want?
