While The Women Are Sleeping

Novelist Kenji Shimizu and his wife, Aya, are set to enjoy a relaxing week-long vacation at a seaside resort. Kenji has been in a creative slump, despite the success of his first novel a few years ago. His doubts have coerced him to accept a corporate job at summer's end. Aya, an editor, pushes him to write, but her ambition begins to create a rift in their marriage.
While lounging at the pool, Kenji notices a couple composed of sexy young woman Miki and older man Sahara. Kenji and Aya joke about this odd couple's relationship, and innocent curiosity plants a seed in the writer's imagination.
The following day, Kenji stumbles upon the couple leaving a local bistro. He questions the quirky owner who then reveals cryptic hints about the couple's past. Kenji becomes even more fascinated, luring him to peep into the couple’s room late at night. He is surprised to see Sahara methodically filming Miki while she sleeps.
Kenji makes contact with Sahara late night at the pool. The possessive lovestruck man confesses his desire to record Miki sleeping daily. Sahara's obsession with beautiful Miki incites Kenji's senses and begins to free him of his writer's block.
But the young man's fixation with the mysterious couple spirals. Kenji becomes a stalker, even sneaking into the couple's room in search for answers. But the more he discovers, the less he understands, except for an escalating sense of danger...
