19-year-old Andrew (Miles Teller) grew up in a single-parent family and wanted to become a top jazz drummer. One night when he was practicing at school, he was spotted by the devil mentor Fletcher (J.K. Simmons) and joined a regular band, and at the same time began to pay the price for the pursuit of perfection. The harder Andrew practiced, the more he was separated from the outside world. The only one who understood him was Fletcher, but the latter's irritability and moodiness distorted the teacher-student relationship, and Andrew was influenced by it, and his own personality also changed. Finally, when Andrew finally stepped onto the stage of the New York Concert Hall, he was horrified to find that Fletcher had been waiting to beat him into the dust... "Whiplash" tells the passionate story of a teenager who, under the supervision of a strict teacher, challenges his limits with unconventional means and pursues his dream of becoming a jazz drummer. The protagonist loves to play drums, but his excessive involvement makes him lose his original intention for music, which then evolves into a burden on life and a nearly crazy duel between the master and the apprentice. The film not only shows the pain of musicians, but also the cruel truth behind traditional inspirational stories. "Whiplash" won the highest honor jury award at the 30th Sundance Film Festival.
