Now her parents Jo, fretful and protective, and Isaac, distant and logical, wait outside her hospital room for the police.

Isaac feels they must let justice take its course, even if it means Hannah pays for their failures. With police drawing closer, their debate forces them to expose deep emotional wounds. What they’ve uncovered cuts to the heart of an even more important crisis within their family.
