This suspenseful crime thriller will keep you guessing until the very end! When a tragedy strikes a marriage, there are a lot of things that go unsaid. Kim Seong Yeol (Cha Seung Won) is a homicide detective with the Seoul Police. He had an affair with a friend’s wife, and on his way home from meeting his mistress, he had a car accident that killed his daughter. Seong Yeol was never able to explain to his wife, Yoo Ji Yeon (Song Yoon Ah), what exactly happened that day and they became noncommunicative because of their shared grief. When Ji Yeon comes home one day with blood splatters on her blouse, she refuses to explain what happened. Then Seong Yeol is assigned to investigate the death of a gang leader, and he is shocked to find one of Ji Yeon’s earrings, a button from her blouse and her unique purplish lipstick color on a glass at the crime scene. Seong Yeol starts to tamper with the evidence to buy himself more time to figure out if Ji Yeon is involved with the crime, but the stakes go up when the notorious gang leader, “Jackal” (Ryu Seung Ryong), tries to find his brother’s killer before the police do and dispense his own punishment. As Seong Yeol tries to stay one step ahead of Jackal, what secrets are they each keeping that could crack the case? “Secret” is a 2009 South Korean film written and directed by Yoon Jae Goo.
