Slocum's on the trail of a mad dog killer... While pursuing the cold-blooded killer Rafe Masterson, Slocum narrowly escapes the outlaw's quick draw with his life. Unfortunately, his trusty horse wasn't so lucky. Slocum's steed was just the latest victim to fall afoul of Masterson, who has two notches in his belt representing the two deputies he's already gunned down. Wanted in several states, Masterson is increasing both his death toll and reward value-and he's not about to let Slocum bring him in...dead or alive.
