When $9,000 worth of gold dust goes missing from a safe in a remote mining town, Wells Fargo sends detectives Henry Johnson and Isaiah Lees to hunt down the culprits. Though the two men are excellent investigators, they couldn’t be more different. Johnson is a Scotsman who relies on instinct and hunches, while Lees is an Englishman who insists on doing everything by the book. Their frustration mounts as neither man can seem to find a reliable witness or solid clue. It’s as if the gold just vanished into the thin mountain air. Years later, gunfighter-turned-newspaperman Bat Masterson travels to San Francisco to meet with Isaiah Lees, now the Chief of Police, to find out how this odd couple of investigators learned to work together to crack the mysterious case.
