Clear Film on top of secondary

[ruscin2]

I noticed today that there is a clear film on top of my brown ale is secondary. Any ideas on what it might be?

Any pictures? Is it scummy or oily? It may be an infection or it may just be hop resin.

It is just like a clear plasticky looking film on top. Hard to get a picture of.

If it is a bit rainbow looking,it might just be hop oils. It'd be easier if you had a pic.
