You see before you two doors, one of them leads to freedom, the other to certain death. There is a guard for each door, one of them always lies, the other always tells the truth. You know not which is which. You may ask ONE yes or no question. What question do you ask to discover the door to freedom?

Keep in mind you're trying to find the Door to Freedom, not the liar, and that you don't know if the liar guards the door to Freedom or to Doom.

I don't know the answer, so don't ask, that's what I'm lookin for lol.
