I must confess that I am shamefully ignorant of the political history of Taiwan, but that didn’t detract from my understanding of what was going on (something I’ve read at least one professional review complain about – ???). As long as you’re not second-screening like a dickhead (and why would you if you can’t understand Mandarin?), you shouldn’t have any problems following the plot of this movie – Detention, or 返校.
