Sam Kellog is a bounty hunter who always takes a sucker’s bet. He’s in debt, can’t keep up with his alimony/child maintenance payments, and can’t resist entering high stakes poker games, because, well, he’s just kind of an idiot. So when a particularly dangerous (and high value) bounty comes up, he can’t resist.
The titular glove is kind of irrelevant to the plot, in the end, but it represents the institutional cruelty of the penal system - it’s a glove designed for use by prison guards, to keep prisoners in their place, except an escaped criminal (and jazz musician) stole one and, um, didn’t really do much with it.
The Glove tries to say something about race, capitalism, and society at large, but it’s just kind of too stupid to manage to put together anything coherent. And it’s not fun enough to work as an action movie, either. Shame.
