Days of Wrath (Korean: 응징자; RR: Eungjingja; lit.

"The Punisher") is a 2013 South Korean film about a man who, having been bullied as a teenager, seeks revenge against the former classmate who ruined his life.

And his girlfriend was raped by Chang-sik in front of him and committed suicide on the next day.

On the other hand, because of his traumatic experience, Joon-seok has a difficult time getting a decent job even though he graduated from a prestigious university; he works part-time as a valet park attendant and frequents a convenience store nearby.

Unable to forget, Joon-seok prepares for revenge to make Chang-sik pay.
