Single, jobless and broke, 30-something Hee-soo is miserable. To get back on her feet she comes up with a plan to track down her ex, Byoung-woon, and re-claim the 3 ½ million won he owes her.
Byoung-woon is also penniless but surprisingly happy for he knows the girls who are willing to give him money. Afraid Byoung-woon may run off before clearing his debt, Hee-soo follows him as he visits many girls to borrow money, so the two ex-love birds set out on a one day journey to collect money, and memory.
Hallucinations and nightmares torment up-and-coming young author Min-woo (Gang Dong-Won). He cannot concentrate on his new work, the much-anticipated follow-up to his first successful novel, nor can he lead a normal life. Old photos and images he does not recognize – though they are somehow familiar – materialize from the darkness as if developed in a darkroom. Haunted by these spectres of memories he can’t remember, he drags himself through days of confusion and alienation. Mimi (Lee Yeon-Hee), a beautiful young woman, follows him around like one completely lost in love. As Mimi intones the notes of “Mist” (popular song from 1960’s) for him, long-ago recollections sparkle in the darkness of his mind as if illuminated by flashbulbs. Flickering memories of his first love claim his concentration, calling for him to remember.
