Season of the Witch (2011)

In the 14th century, Behman and Felson are warriors for the medieval church who decide to desert after they are ordered to kill a town full of people, including the women and children.  They stop in the first town they arrive in to get supplies and refresh their horses.  But they are arrested when the design on the hilt of their swords reveal they are Templars.

The two are tasked with transporting a witch to an isolated abbey for a trial. The witch is blamed for causing a plague that's running rampant, as plagues are known to do.  The monks at the abbey have a book filled with rituals that can destroy the witch and her power.

Behman and Felson take on the task, as they have no other choice. But since they are soft hearted regarding women and children, they insist that she be treated fairly.  It's the wise cracking knight,  feel good, witch movie of the season.
