The premise is enough of a murder-show Mad Lib to suggest, correctly, that a creator of this caliber won’t be taking it at face value. Three childhood friends are summoned to the wake of the estranged fourth member of their high school clique, with whom they shared an awful secret. In a series of flashbacks, we’re gradually given context for the haunting image of four girls watching fire consume a cabin. Now pushing 40 and navigating various midlife crises, the women are ensnared in a tangle of new and old mysteries. Relevant clichés include: You can’t go home again. Hurt people hurt people. The past is never dead. It’s not even past.
