Mr Bachmann and his pupils (aged between 12 and 14) live in Stadtallendorf, formerly the site of a secret Second World War munitions factory and now an industrial town that’s home to generations of economic migrants.

All the while, their sexagenarian, rock band T-shirt wearing teacher’s effortlessly egalitarian approach encourages students to develop empathy for one another through openness and listening.

Shot over six months, Reinhold Vorschneider’s patient cinematography works with the spontaneity of the classroom environment to lend emotional weight to even the most fleeting moments. The pacing and observational method call to mind the work of Frederick Wiseman, yet Speth’s intimate approach creates an engaging and tender drama.
