Memoir of a Murderer

“Memories can deceive you.”

Byung-su (Sul Kyung-gu), a retired serial killer with Alzheimer's, watches his daughter Eun-hee (Kim Seol-hyun) bring home a new boyfriend, Tae-ju (Kim Nam-gil), and recognizes a killer in him. He is sure of it. Won Shin-yun builds the film around Byung-su's failing memory, so his certainty can't be trusted, and he has only a shrinking stretch of lucid days to keep Eun-hee safe.
