Daniel Levitt is a Nazi hunter working in Western Maryland in 1993. He is on the trail of Dr. Karl Mueller, who is responsible for the deaths of thousands of Jews in the WWII concentration camps. At first, Daniel is uncertain why Mueller has come out of hiding to go to a small town in the Maryland mountains. However, Daniel soon discovers one of the town’s secrets, Esau Lachman.

Esau is the son of Eva Lachman who survived Mueller’s experiments during WWII. Esau is the result of one of those experiments, a human-gorilla hybrid. He was supposed to be the first of many disposable Nazi super-soldiers, but the experiment went awry. Esau is a twin, although he and his brother, Jacob, appear to have little in common. Jacob is a murderer while Esau is the one who looks like a monster.

Now Daniel must decide whether protecting Esau’s future is worth getting justice for the past.
