On a dangerous rural highway, two teenage girls wreck their cars exactly two years apart. Sarah was driving sober in broad daylight, Mal was driving drunk at 3 a.m.—but it’s only Mal who survives. When Mal encounters Sarah’s ghost at the crash site, she’s forced to consider why she’s still alive and looks for ways to help her new ghost friend. Meanwhile, Mal’s mom, feeling guilty at the injustice of her daughter’s survival, befriends Sarah’s grieving mother. Through these unusual, fraught friendships, the four women search for purpose behind their unfair fates.
