After one night of drinking, an owner of a gay sauna, an accountant, and a student all switch bodies.
After a wild night of drinking a mysterious ancestral wine in a hot spring, three unlikely friends—A Bu, the flamboyant owner of a gay sauna; Hua Hua, a no-nonsense accountant; and Xiao Chi, a shy college student—wake up to find their souls have swapped bodies! Now, a burly middle-aged man must navigate life as a young woman, a reserved student is trapped in the sauna owner's confident skin, and an effeminate gay man experiences dating from a straight guy's perspective. This hilarious and heartfelt Taiwanese series uses its supernatural body-swap premise not just for outrageous comedy, but to explore identity, empathy, and the messy, beautiful complexity of love and friendship. Set against the vibrant backdrop of a gay sauna, the trio must juggle each other's jobs, relationships, and personal secrets while trying to find a way back to their own lives. With sharp acting that lets each performer shine in multiple roles, two different endings, and a refreshingly respectful take on LGBTQ+ characters, 'Mermaid Sauna' is a short, sweet, and surprisingly deep dive into what it truly means to walk a mile in someone else's shoes.
