In a dystopian future where Kansai became a vassal state of Kantō, multiple highly skilled criminals, called "Akudama," are sent a message from an anonymous client to free a death row prisoner named Cutthroat before he is executed. Four Akudama respond to the challenge and descend into Kansai Police Headquarters to earn a big payday. However, once inside, they discover the job was part of a larger scheme by their client to make them work together on a bigger job: to infiltrate the Shinkansen and steal precious cargo from a vault at the front of the train. Roped into the job are an ordinary girl arrested on a minor charge but forced to keep up the appearance of a Swindler, and a low-level Hoodlum who was accidentally broken out of jail during the initial heist. The team must work together to finish the job and earn their large payday, all while keeping ahead of the Executioners from the Kansai Police on their tail. Source: Wikipedia
