Dutch colonial army in West Java holds a martial arts tournament to select the best warrior to confront local warrior-freedom fighter Parmin (nicknamed Jaka Sembung). The winner is an obscure blind swordsman and the Dutch commander De Mandes (Gino Makasutji) commissions him. However, the swordsman is sympathetic with Jaka Sembung’s cause and things get more complicated when magician seductress Dewi Magi as well as her guru (W. D. Mochtar) intervene on behalf of the Dutch.
