Respect your teachers, folks. They're underpaid, underappreciated, and if you push them to the edge, well, good luck. That's the core message of the Saoirse Ronan-led dark comedy thriller Bad Apples, which has a trailer out today.

Directed by Jonatan Etzler and written by Jess O'Kane as an adaptation of Rasmus Andersson's novel De Oönskade, the film sees Ronan as a Somerset-based primary school teacher named Maria. She adores teaching, but the underfunded education system wears her down on the daily. When her disruptive student Danny (newcomer Eddie Waller) spins out of control, Maria makes some choices.

As I wrote in my review out of BFI London Film Festival, "With Ronan's always-impeccable talents supported by a sublime young cast, Bad Apples leans into unethical impulses, all the while exposing home truths about the under-resourced education system and social disdain toward children with behavioural, emotional, and social difficulties. Plus, it's really funny."

Bad Apples hits cinemas Sept. 18.
