The setting is Stanton Wood, an austere British reform school for troubled teenage boys. Cillian Murphy plays the title character, an aging headmaster doing his best to help. Over the course of one chaotic school day, he navigates skirmishes with bright, rowdy students like Shy (Jay Lycurgo) and Jamie (Luke Ayres). But how does he navigate his own trauma, as well as the possibility that his beloved school may be shut down? Tim Mielants, of Small Things Like These, directs. —Elena Clavarino
