Anaereul Jugyeotda(2010)

After drinking with a friend, Jeong-Ho falls asleep and wakes up the next morning with a hangover. The next morning, he hears the shocking news that his estranged wife, Mi-Young, has been murdered. At that moment, Jeong-Ho discovers bloodstains and a bloody knife on his clothes. He is identified as the strongest suspect and runs away from the police. Jeong-Ho wants to prove his alibi, but his vision is blacked out due to drinking the night before. He tries to prove his innocence by holding on to the fragments of memories that come to mind one by one and by tracking his whereabouts the night before based on the statements of other people around him, including a friend who drank with him the night before. However, as he pieces together his memories and the stories of those around him, he comes to the conclusion that he might really have killed his wife.
