Peter ‘Mad Max’ Maxwell, the ‘dinosaur’ Head of Sixth Form at Leighford High, just cannot get to grips with technology, and doesn’t see the need to know how to send a text or an email when a simple note or phone call will suffice. However, it soon becomes vital that he learns when some of his female pupils begin to receive strange and threatening messages, with the anonymous sender claiming to know intimate details about the girls’ personal lives. Max starts to receive messages too, and then two of the girls go missing. When a body is found it seems that the prank has taken a sinister turn, and Mad Max may well be the next target. Is the chance of him reaching retirement looking more unlikely by the day?
