The camera is inside this plane!
If you have a look at the messages (which is actually always a good idea) 
you'll see something like this:
Warning: Camera is inside a non-hollow object. Media and fog may not work 
as expected.

Btw, please post the shortest example that is neccesary to show the problem 
next time. This also often helps to find the mistake oneself.
