[TOMT] Can anyone help me identify this movie? (post-2000 psychological thriller in upscale nightclub/bar)

Hey, I’m trying to find a movie or TV show I watched sometime after 2000 and I can’t remember the title.

What I remember:

  • It takes place in a modern, upscale nightclub or bar for wealthy people
  • The interior felt very stylish and luxurious, almost like a mansion
  • There was a large staircase in the middle connecting two floors
  • I think there might’ve been a hidden or restricted room in the building
  • A group of people go there for a night out
  • They end up stuck inside after closing time
  • After that, people start dying one by one in mysterious ways
  • It’s unclear if it’s a killer, supernatural force, experiment, or psychological situation
  • The whole thing feels very paranoid and claustrophobic

I’m not 100% sure on all the details, so some things might be slightly off.

If anyone recognizes this or something similar, I’d really appreciate it.

Trying to find a movie/TV show — upscale nightclub, locked inside overnight, people dying one by one (post-2000)

Hey, I’ve been trying to identify a movie or TV series I watched (released sometime after 2000), but I can’t seem to find it anywhere. I’ve already asked a few AI tools, but they keep giving me incorrect titles, so I’m hoping real people might recognize it.

I also attached some images that represent the kind of look and atmosphere I remember from the film.

Here’s what I remember:

  • Genre / tone: Psychological thriller, mystery, suspense
  • Setting: A modern, upscale, luxury nightclub or bar for wealthy/elite guests
  • Interior design: Very sleek and atmospheric, with a mansion-like feel
  • Key feature: A large, elegant staircase in the center connecting two floors
  • Hidden element: There may be a secret/restricted room or hidden chamber inside the venue
  • Main plot setup: A group of friends/guests go there for a night out
  • Inciting incident: They end up accidentally or intentionally locked inside after closing time
  • Main conflict: People begin dying one by one inside the locked location
  • Mystery element: It’s unclear whether it’s
    • a real killer
    • something supernatural
    • a psychological experiment
    • or hallucinations/paranoia
  • Overall vibe: Claustrophobic, paranoid, and increasingly chaotic as the group tries to figure out what’s happening

I’m not 100% sure about every detail here—some parts might be slightly off or something I’m misremembering—so I’m also open to anything that’s just similar in vibe or setup.

Any help would be appreciated.

Update: I might actually be mixing up details from 2 different movies or shows, so some of the description could be combined or slightly wrong. I’m also not completely sure about the country of origin — it could be from the US, UK, Thailand, Japan, or somewhere else.
Just wanted to add that in case it helps narrow things down. Thanks again for all the suggestions so far!
