Can someone please tell me the name of the t.v. show that had a female ninja in it?

I know there are a lot of shows like this but I remember a specific one probably only a few years old and I really want to watch it....the problem is i can only remember glimpses of it...like three people are climbing a mountain and the rope is breaking so the ninja girl has to cut one of the guys down even though she needs them both....and a fight in a living room....and a scroll?? THANKS TO WHOEVER ATTEMPTS THIS QUESTION...OR TO THE FUNNY COMMENTS PEOPLE MAKE. I LOVE THEM ALL.
