Forgot your Netflix series name?

So I want to watch a Netflix series only the problem is that I forgot the name. I know about what happened there, so I hope that this description will help.

So I remember that I believed four people were abducted and locked up in a cellar in cells like that. The people are then gasbed to sleep and one is then taken to an apparatus by the kidnapper and he drowns them. But somehow they come back to life and nobody remembers anything. In the end, two people say they were able to break out, so children could experience what they saw there. Can anyone do anything with this info? I thank myself.

The series is called OA
