This drama is adapted from the manga of the same name. In the first episode of the TV series, "The Battle for the Tattooed Prisoner in Hokkaido", the operation to hunt down the tattooed prisoner with the code indicating the location of the gold nugget officially begins. The journey of the gold nugget enters a new stage, and the prisoners' pasts and beliefs are also revealed. The three-way battle for the tattooed prisoner between the powerful characters who appear one after another and the 7th Division (including Lieutenant Tsurumi) and other factions is also very fierce.
