It seems to be a simple story taking place at school, but it draws your whole attention to watch till the end of it. School teacher Luk is asked to bail his student Chan out, as Chan tries to climb up a flyover to put up a banner in a demonstration. The next day, some paparazzi rush to school to shoot Chan and ask for quotes. Unfortunately one of them slips and the media reports come out in a negative way. The school is highly alerted and Chan is suspended without investigation. The suspension, indeed, has nothing to do with teaching or guidance, but solely political correctness and administration issue.
