Netflix’s Tight Security Shocks Cast of “The Devil’s Plan 2”: “Umbrellas and Bodyguards Just to Use the Restroom”

On May 9, a behind-the-scenes video titled “[SUB] The Return of the Brain Survival Game! Behind-the-Scenes Review of Episodes 1–4 of The Devil’s Plan: Death Room” was released on YouTube channel TEO, featuring key cast members including Lee Sedol, Kyuhyun, Kang Ji-young, Yoon So-hee, Sevenhigh (Jung Seung-mook), and more.
The cast gathered to reflect on the first four episodes of the high-stakes survival game, which premiered on May 6, and the discussion quickly turned to Netflix’s over-the-top security protocols—so strict they even shocked seasoned celebrities.

Professional poker player 7high shared a moment that left everyone stunned: “At one point, someone went to the restroom, and they were escorted with umbrellas covering both sides.”
The dramatic measure, meant to prevent contestants from seeing or interacting with each other outside of the filmed games, became a running joke among the cast—but also highlighted the extreme lengths Netflix is taking to avoid leaks and spoilers.

Former announcer Kang Ji-young confirmed, “I’ve never had that level of protection before. Two bodyguards followed each person. Did anyone accidentally see someone outside?” Fellow contestant Tino added, “Not at all. No one saw anything until the moment we opened that door and walked in. I remember there being a lot of Carnival vans. I kept thinking, ‘Someone must be in there’.”

With the show’s twisted puzzles, celebrity mind games, and secret strategies, The Devil’s Plan: Death Room has already built a reputation as a must-watch brain survival series. And with Netflix investing in cloak-and-dagger-level secrecy, the stakes feel higher than ever.
From umbrella escorts to bodyguards for bathroom breaks, one thing’s for sure—on The Devil’s Plan, what happens behind closed doors truly stays behind closed doors.
