Korea’s first serial killer struck in the countryside around
Hwaseong in the 1980s; he was never caught.

Bong’s masterly reworking of the case centres on the
bungled police investigation (the great Song Kang-ho plays
a thick-eared local cop) and identifies as prime suspect a
man who looks like a leftist student-turned-manual worker.
What’s really on trial is Korea’s own authoritarian past.
