Just saw, the Chaser, a Korean movie
"Joong-ho is a dirty detective turned pimp in financial trouble as several of his girls have recently disappeared without clearing their debts. While trying to track them down, he finds a clue that the vanished girls were all called up by a same client whom one of his girls is meeting with right now. "
It's one of the best films I seen in a long time. Never a dull moment
