PIT PULLS was based on a comic by Mike Richardson (TIMECOP) & Jerry Prosser and similar to the likes of UNIVERSAL SOLDIER, SOLO and SOLDIER: a perfect soldier in between a human and a machine who discovers himself a soul and emotions and turns against its creators...

From birth, the government taught him that emotion didn't exist, that compassion was worthless, that his life was worth nothing next to the good of the squad. And they taught him to kill better than anyone else in the world. But now he's on the loose and learning that he has a soul--and the first thing he feels is hate.
