So, when Blake suddenly announces he's gotten married, Sandra can't shake the feeling that something is off. Why rush? And why keep such a huge milestone a secret from your best friends? When she finally meets Tara, Blake's new wife, Sandra's unease only deepens. Tara is cold and distant, and something about her just doesn't sit right.

As Sandra pieces together the last moments of their trip, one name keeps surfacing-Tara. Now, Sandra is left with a terrifying question: Did someone make sure Alex never came back from that mountain?
