Gabimaru regeert als de sterkste en meest meedogenloze moordenaar in zijn dorp. Maar nu bevindt hij zich in de dodencel – met maar één uitweg: het levenselixer terughalen van een sinister eiland. Verlangend naar vrijheid aanvaardt hij de uitdaging. Maar hoe zal Gabimaru deze aangrijpende zoektocht overleven, nu zijn medegevangenen strijden om dezelfde prijs en demonische beesten op de loer liggen?
