So I know this is going to be a difficult one. Thank you in advance for reading this.

I saw this on some movie channel on DirecTV (or whatever we had then) when I was a preteen. It was shot sometime in the late 60s or 70s.

All I can remember is some woman who wakes up completely naked and starts slowing walking, trying to leave the building. She doesn’t care that she’s naked and, as she’s slowly leaving, security guards are trying to shoot and kill her but she’s either a) killing them or b) the pills can’t hit her. I can’t remember which it is. Also, if it helps, I remember her descending some large stairs in a large, open room.

I know it’s a long shot but I would seriously love some help. It’s been killing me (no pun intended) for years!
