Evil Dead III Army of Darkness (1992)-NISHIKONAMIKO

After being pulled through a time portal, Ash Williams lands in 1300 AD, where he is almost immediately captured by Lord Arthur's men, who suspect him to be an agent for Duke Henry, with whom Arthur is at war. He is enslaved along with the captured Henry, his gun and chainsaw confiscated, and is taken to a castle. Ash is thrown in a pit where he fights off a Deadite and regains his weapons from Arthur's Wise Man. After demanding Henry and his men be set free (as he knew Henry was innocent, and his persecution was simply a witch hunt) and killing a deadite in full view of everyone, Ash is celebrated as a hero. He also grows attracted to Sheila, the sister of one of Arthur's fallen knights.
