I asked an AI to write a western plot and this is what she said.

Here is one possible plot with a twist for a modern western about an outlaw Marshal hauling a wanted war criminal back to jail while his gang tries to ambush and set him free:

In the modern American West, a notorious outlaw named Jack McCall is tasked with transporting a wanted war criminal named Marcus Johnson back to jail. Jack and Marcus set out on a dangerous journey, with Jack’s gang following close behind, planning to ambush them and set Marcus free.
