Whiplash
The third act of Whiplash sees Andrew (Miles Teller) arrive at the JVC festival concert, ready to play the drums again after a coincidental reunion (and subsequent invitation) with Terence Fletcher (J.K. Simmons), whom Andrew got fired from Shaffer Conservatory of Music, although Fletcher is also the one who expelled Andrew. In an act of revenge, Fletcher attempts to humiliate Andrew on stage, but Andrew prevails, pouring himself into a drum solo that ends up impressing the man who set out to destroy him.
