Oasis (2023 Korean Drama) - Season 1 - Episode 1

Across the season, the narrative follows the escalating manhunt inside the sealed resort: initial shock and containment give way to pointed interrogations, conflicting alibis, and leaked rumors; red herrings multiply as staff and guests are exposed for affairs, debts, and cover‑ups; and the investigation closes in on a small circle with means, motive, and opportunity, culminating in a reveal that recontextualizes the disappearance and the true purpose of the lockdown.
