Mike Greco is just an ordinary student at Seoul University that spends his days hanging out with his conspiracy-enthusiast friend, Dexter. After an unsuccessful blind date with Dexter’s friend Angelina Wayne, Mike and Dexter go drinking at a bar, where they have an argument with the brawny Juan.

However, Mike opens his eyes and suddenly sees that it’s morning! He has no recollection of what happened after drinking, and neither do Mike and Juan. Reaching into their pockets, they find a cryptic card with a hanging doll on the front and the words, “Where does your memory begin?” on the back. But they’re not the only ones with cards, and the answers to this question seem to lie in 1994, where a mysterious crime they’re connected to occurred… What will happen when the memories come back?
