Gruff Garrett is an old US Marshal. He's pushing a little past sixty now, and he's starting to feel the wear and tear of age. Time shows no mercy to anyone as Gruff starts to feel a lot weaker, with a shorter step, trembling hands, and a ticker that always seems to threaten to give out. Gruff is always wondering if it's time for him to call it quits and retire. After all, it's clear that his best years as a marshal are behind him. Or are they?

Gruff just can't turn in his badge and retire as a US marshal. After all, it's all he's ever really known to do in his life. After Ma Edgar Hoyce, an old lady who leads a family of robbers and murderers robs a local bank, it's up to Gruff and two other much younger US marshals to track her and her murderous family down. Gruff thinks he knows where Ma Edgar and her vicious kids are but the young marshals doubt his capabilities. They question his competence because of his advanced age, but Gruff pays them no heed.

The two younger men take one path and Gruff takes another. Gruff takes the right path and manages to track down Ma Edgar and her vicious family. He's found them now, but can he survive a gunfight against them.
