Code Red for Green Star Phal!

Help, help, help!
So I was in a co-workers office space last week, and noticed the cutest little orchid sitting between their 2desks. Not wanting to offend, did not ask whether it was real or not (it was THAT pretty, and I've never seen one of these before. I'm a permanent newbie!)
Today, I walked into the same space, only to find that the poor plant had gone south. When I asked what happened, I was just told - "we are going to throw it out, do you want it?". I can't see plants being thrown out, so I grabbed the poor little darling and brought it home.
The spike and the blooms have gone black. Not sure what it's all about. The leaves look reasonably healthy, but the root system looks like it can use some help. I just don't see the plant to 'secure' to its medium.
Can anyone help?
This is my first time on the boards, so I hope my photos come through.
