Alter Ego - Season 1 - Park

Park, a 25-year-old Korean man, basks in the sweet tropical sun of a luxury residence in the company of various other people of diverse backgrounds. They're all waited on hand and foot by a team of servants and carers. He spends most of his time with a couple of fun young women. It's paradise. But lately his blissful existence is punctuated with strange hallucinations, like memories of another life. Might this change in his state of mind be because he's stopped drinking the delicious fruit cocktails they keep serving up to all the residents? And what are they all doing here anyway? Can they really just be on permanent vacation? But then why are there all these railings and watchtowers?
