Twenty years ago a plane with a high school girls soccer team crashed in the Canadian Rockies. In an initial scene we see a flashback from the woods, and it is not pretty – there is a bizarre ritual and implied cannibalism. In present day, three of the survivors are living their lives when some receive a reminder of the crash, which they perceive as a threat. The show moves back and forward from the time of the crash and present day – exploring the various relationships, slowly starting to unfold what happened in the past, and dealing with the present fallout.
