Walter (2019)

An imposing but kind and gentle black guy, Walter works as a security guard at a supermarket. One night, a team of burglars, consisting of the determined Victor plus 4 rough-edged and ill-disciplined youngsters, deliberately trigger the alarm to get Walter to come and open up the supermarket. But the robbers never imagined they'd be dealing with not just the stereotypical "brave" security guard but a former African warrior intent on foiling their ill-advised robbery attempt.—Happy_Evil_Dude
