The story, without the spoilers.
Seo Jung-hoo works as a night courier under the code name Healer, taking on dangerous jobs for clients who pay well and ask no questions. He is fast, clever and almost invisible. Then a job brings him into the orbit of Chae Young-shin, a spirited entertainment reporter chasing a story about a past tragedy, and Kim Moon-ho, a famous journalist with his own reasons for digging into the same old case. As the three of them pull at the same thread, a decades-old conspiracy begins to unravel. Healer is pure entertainment: stylish action, rooftop chases, disguises and a romance that grows naturally out of trust rather than instant attraction. Ji Chang-wook is superb as both the cool courier and the awkward young man underneath, and Park Min-young matches him with energy and warmth. The conspiracy plot is twisty and occasionally over-complicated, but the action, humour and chemistry make it one of the most rewatchable thrillers of its decade.
A little curiosity. A new favourite.
