Jenny channels her grief – and secret guilt – into an obsession with getting pregnant again. Ella, a competitive high school cheerleader, is desperate to atone for her role in the tragedy by being the perfect adolescent for her heartbroken parents, but secretly cuts herself to numb her emotional pain. Not without his own vices, Riley’s dad Ethan, a pilot, is on a singular mission to preserve what’s left of his family – to little success. Everything changes, though, when Ella makes a shocking decision.
