Scandal in Chinatown

Hot fans of Sherlock Holmes, the fiery-haired brothers Old Red and Tough Red Amlingmeiers finally hang up their spurs and move to the dangerous streets of San Francisco, hoping to become private detectives. Despite the former cowboys' weak familiarity with city life, one thing remains unchanged: the unparalleled talent of Gustav and Otto for getting into trouble.
Spotting their recent acquaintance Dr. Chan in the depths of Chinatown, the brothers quickly get caught up in the confrontation between criminal gangs, thugs from the Barbarian coast, and the local police. 

The plot thickens, and it remains to be seen whether the inseparable Reds can save an entire city from disaster before it's too late.
