Please answer the following question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: The Chaser Movie plot: Eom Joong-ho is a dishonest, ex-detective turned pimp who is in financial trouble because two of his girls have gone missing. One night he sends Mi-Jin, one of his few remaining girls to a customer. But he later realises that this is the same person who was the last to see his missing girls. Believing that this man is reselling his women, he goes to look for Mi-Jin. On the way he contacts his old police task force to ask for some help. But they cannot assist because the Mayor of Seoul, who they are guarding, has just been attacked with human faeces during a walkabout. The police are now preoccupied with a media storm because they have suffered humiliation for failing to protect the mayor.Mi-Jin wakes up tied in a dingy bathroom. Her "customer", Je Yeong-min, comes in with a bag of tools. He tells her that a previous victim had her tongue cut out for screaming too much. Using a hammer, he tries to drive a chisel into her head. But she resists and he hurts his hand. Moments later callers from the local church arrive at the house inquiring about its owner, Mr Park. Yeong-min has no time to finish off Mi-jin so he invites the elderly couple in and butchers them.But while searching the area for a parking spot in an attempt to ditch their car, he collides with Joong-ho's vehicle in an alleyway. Joong-ho senses that the man, Yeong-min, is hiding something because he will not give him his phone number. Joong-ho calls the customer's number establishing this is the man he wants. Yeong-min tries to run away but is caught and badly beaten by Joong-ho. On returning to the collision, both men are arrested by a suspicious local cop. At the station, Yeong-min admits he has killed up to nine people but hints Mi-jin could still be alive. A fracas starts when competing divisions all want to investigate the previous high-profile unsolved murders in the area. The chief arrives and throws the book at everyone because of Yeong-min's injuries. He is concerned the beating will be picked up by the media following the night's earlier... My question: Who does Yeong-min collide with?
Answer:
Joong-ho
