Delitto nel porto

In a corrupt and silent Boston, the pards must catch Wayneka, a rebel Navajo accomplice of the band of arms traffickers of Paul Beaumont, an ex revolutionary Corsican who controls the police captain, Corbett, and uses ferocious thugs like Requin. The gang, after having done away with the by now troublesome Indian, lay a deadly ambush for the rangers who, however, leave them empty handed, thanks also to Pierre Touissant, a black Pinkerton agent who is investigating the same contraband of guns under a false identity.
