Sleepy Eyes of Death: In the Spider's Lair (1968)

This film of the sleepy-eyed ronin series finds the anti-hero in an area where the locals are oppressed, suppressed and held against their wills. Part of the coercive forces trace back to the lord of the area and for the swordsman to rise, resist and fight he first has to wade his way through a number of traps and assassins, except luckily a couple of them are female and attractive and hence desirable in bed.
