What Perfect Number Is About

A quiet mathematics teacher learns that his neighbour has killed her abusive ex-husband, starts thinking on her behalf, and builds a plan that rearranges the entire question of suspicion around himself. The tension comes not from the killing but from watching the police try to take that structure apart, and the real question the film is asking is why he does any of it at all. Adapted from Keigo Higashino's novel The Devotion of Suspect X, which had already been filmed in Japan in 2008. Pang Eun-jin directed this Korean version.
