Lost synopsis……Through the Looking Glass?????

Anyone know where I can get the synopsis for the season finale “Through the Looking Glass”? It’s not on abc.com. On the episode guide the last one is “Greatest Hits”. I taped the finale because I was moving and I just started to watch it last night and half way through the sound went out. I could still see the picture but no sounds so I wanna read the synopsis. Thanks so much!!!!
