Tuskers II: Day of the Long Pig

Barry and Jenny inherited a fortune, with a single stipulation: that they hunt down and eradicate the Tuskers. They can only hope the Tuskers are gone. They aren't sure they can follow through on the genocide of an entire new species.

Genghis, the smartest and most ruthless of the Tuskers, survives. Deep in the desert, he breeds with the wild pig population. These mutants are able to learn from humans...and quickly surpass them.
