The dark mystery stars Mikuni Rentaro's boy Sato Koichi, model & fledgling actress Kiki (Asano Tadanobu's kinky admirer in Tsukamoto Shinya's "Vital"), unsettling beauty Kimura Tae, and the always reliably gruff Emoto Akira.
Here's a synopsis from the official press kit:
Yuichi Arisu (Sato) slaves away in a cold, geometrical office everyday, in a humdrum job, somewhere in the huge, impersonal city of Tokyo. Every night he commutes home to his distant wife (Kimura), and buries himself in the mystery novels of Jo Kuroda, a writer who has conjured up a strange universe called the Darkland.
Then, one night, his wife disappears. The following day Arisu falls asleep on the train on his way home and wakes in a siding to find jo Kuroda sitting opposite him. The writer persuades Arisu to tell his own story. So begins a second story about events that took place two years ago in a snow-bound town in the far north of Japan. There, in the eerie, crumbling Starfish Hotel Arisu begins an affair with a young woman called Kayoko (Kiki).
Is Arisu's story a memory, a dream or just a story? As the plot in the past unfolds the present day story of the search for his wife also becomes more and more bizarre, Arisu traces his wife to a private detective and then to an underground brothel called Wonderland. But the brothel burns down and the detective is murdered. Arisu becomes the main suspect in a murder case. Then the walls between fantasy and reality break down completely when Arisu stumbles into the Darkland...
