Fist Fight (2017) on Netflix

On the last day of school, right on Senior Prank Day in Roosevelt High, things don't look good for meek English teacher Andy Campbell, who feels exceptionally expendable facing a bleak future in front of severe job cuts, just before the year's new school season. But soon, things will go from bad to worse when feeble Campbell will infuriate the scary hot-headed history teacher Ron Strickland, who in turn, he will challenge him in an old-school, no-holds-barred, mano-a-mano throwdown in front of everybody, in the parking lot after school. Inevitably, now that the fight is on, no excuses, no regrets, and certainly no talking sense into Strickland, is going to save Campbell who needs to face the consequences of his actions and pay the heavy price. After all, snitches get stitches.
