Bullet Train: This is the name given to the Shinkansen train on the Tokyo - Kyoto route, as it races back and forth between the two cities at an incredible 320 kilometers per hour without stopping. Getting off is impossible. Also on board the Shinkansen is Ladybug, a down-on-his-luck hitman who is to take out his next victim on the high-speed train. After a few setbacks for Ladybug, this time everything simply has to go well. But this job won't be easy either, as there are five other hitmen on board: Tangerine, Prince, Hornet, Lemon and Kimura. Surprisingly, not all of them are after the same target - and yet their missions seem to be connected. Naturally, the ice-cold contract killers get in each other's way and a chaotic fight to the death breaks out on the high-speed train.
