How does the greatest gunslinger of the old west end his career? By hunting a dinosaur animal spirit, of course.

Karl Redgrave has a big plans for his retirement party. He's bringing together the world's greatest criminals, murderers, warriors, and assassins to hunt something worthy of them all: a highly intelligent, seven-foot tall dinosaur spirit; known to the natives as the Grishla.

Of course, Karl wants only the best on his safari, so he has pitted these men against each other in a deadly contest in an old ghost town, with five winners securing a place in the hunt.

Who will live? Who will win? And if they win, can they survive the final confrontation with the beast?
