Leaves with brown spots. brown stem. no flowers, help!

[tim o tay 89]

This orchid had flowers up until a few weeks ago. We got it from my grandmother, and found out that it was SOAKED in the roots, with at least an inch of water at the bottom of the pot. It has since been draining, but I'm not sure what to do (if anything) to save the flower. The stem has turned brown and the leaves have these little brown spots on them, some all the way through the leaf.

If there's anything that can be done to save this orchid, please let me know.

I've attached a few pictures of the orchid below.

Thanks
