Shadow boxing is a training exercise where the boxer trades blows with their reflection. In other words, a shadow boxer is someone who fights themself.
Shadow Boxer is the name Jannis Lenz gave the title character in his 17-minute short portrait, in which 23-year-old Ahmet Simsek faces a turning point. Ahmet, a kickboxer, is sentenced to probation for assault, and he has one final chance: If he’s given a positive evaluation after an anger-management training, he won’t have to go to jail.
