"The Gunner" tells the story of Kobayashi, a talented high school student, who made huge profits by cheating in an international exam for a rich boy, and planned a perfect cross-time-zone cheating with Bank, another talented student with excellent memory.

The play is adapted from the cheating case in the examination room that caused a sensation in Asia in 20 14. It not only captures the same memories of studying for exams as a student, but also breaks the impression of small affection and love in previous campus movies, and captures the uniqueness of everyone under the examination system.
