Description
There’s always a price to pay…
Jess Burton and his sidekick Shorty Pearson ride into Yellow Gulch, desperate to find work after months on the road.
They enlist into Wilton de Brock’s company, despite the fact that the pay is bad and de Brock’s reputation even worse.
But after just a day of hard labour for barely any money, Jess realises the injustice of de Brock’s business.
Talking to others in the camp, he realises what he has signed up for. De Brock treats his workers like slaves, with whippings common practice.
Escape seems impossible, with de Brock having a firm grip on not just the work camp, but the whole of Yellow Gulch.
Even the Mayor and the Sherriff are wrapped around his finger.
But it doesn’t take the swashbuckling Jess long to take action, and when he kills one of the brutal guards, he has no choice but to try and escape.
Jess makes it out to the countryside, where he meets Len Calvert and his rebellious daughter Fay.
He explains his plan to the Calverts, about how he’s intending to rescue the other workers and overthrow de Brock’s brutal regime.
Len Calvert wants nothing to do with it, but his daughter is inspired by Jess’ sense of justice.
Jess frees the workers and joins forces with Fay.
But will Jess be able to overthrow the ruthless de Brock?
Or will he lose his life, like all those that have tried and failed before him …?
