The fifth and final season chronicles the aftermath of last season's horrific events and finds the characters coming to terms with the consequences of their choices – as they make the realization that if they really want to change their futures, they must first face the past. Helen begins the season involved in an intoxicating new affair. Noah meanwhile has to swallow his pride and his jealousy and step in to take care of his family in her absence. But just when things seem to have stabilized, a chance encounter with someone from the distant past sets in a motion a sequence of events that brings them both to their knees.
