The Gangers: High Noon in Yorkshire

The avenger rides into town looking for the men who killed his friend. In his saddlebag, he carries a Colt 44. But this is no wild west scenario.
This is Yorkshire. The avenger is Sergeant Lorenzo Joseph of the British army. And the background is the Railway Boom of the 1870s.
This is a world where progress and poverty, industry and anarchy combine in a volatile mix. The shanty towns of the railway-building navvies are as lawless as the cattle towns of the American west.
But there is a more gentle, civilised side. Sergeant Joseph encounters Mollie Proudlove, the poetry-loving, 12-year-old daughter of the local vicar. And she falls innocently in love with her handsome knight on a white horse.
Meanwhile, in the darkness of the shanty town, gang leader Moleskin Jimmy lies poised to strike again – at the Sergeant, at Mollie, or at anyone else who gets in his way.
In this situation, how can justice triumph and innocence survive?
