Penguin

In a world where implanted neural chips allow investigators to interrogate suspects through their own memories, detectives Kim Jinyeong and Seo Jisu prefer the old-fashioned method of chasing criminals on foot. Officially, they are colleagues-turned-lovers who divorced years ago; but off the record, they continue to seek each other out after work, haunted by a tangled relationship that neither has fully let go of. Then, one chilling Christmas night, Jinyeong disappears without a word. Exactly one year later on Christmas Eve, he returns and stands before Jisu as if nothing had happened. Where has he been, and what truth hides behind the silence of that missing year...?

After winning tickets to an old theme park on the outskirts of Tokyo, Casio and his friends brave the eerie rumors surrounding the place for a little winter adventure. However, what was supposed to be a fun day trip takes a horrific turn when one friend lures Casio away from the group—and stabs him to death. While he bleeds out, his friend tearfully begs him to save someone named Asebi.

When Casio next awakens, time has rewound to the moment he set foot in the park that morning. Though he's shaken and desperate for answers, his "second" day goes by without incident—until he tries to leave and snaps right back to that morning again. As he spirals into panic, a mysterious girl appears and introduces herself as Asebi. She tells him she's been trapped in the park for a long time, reliving the same day over and over. Now Casio is caught in the loop as well...and according to Asebi, the only way out is to kill someone.
