The Beheading

A female Russian jihadist attempts to make a video of the beheading of an American reporter. It's a war zone however, and incoming artillery fire wounds her in the shoulder as she wields the knife. Orders come in by a walkie-talkie to retreat, so she leaves immediately. The reporter uses the knife she left behind to cut himself loose then, understandably enraged, sets out on a mission of revenge: to cut her head off. Nonstop action ensues until the gripping conclusion.
