Grand theft cobra venom? That is what seems to be the charge, along with murder, when a robbery attempt of an Asian ship goes wrong and leads to a wild gunfight. A longshoreman is killed and another one is wounded, but steals his assailant's gun, kills him and makes off with a large shipment box supposedly full of cobra venom to be used in research. The wounded man goes into hiding on the docks with the gun and the case, believing he has actually stolen a shipment of much greater value. He meets secretly with a priest and refuses to turn himself in. Meanwhile, Stone and Keller have traced the dead robber to a Mafia unit in San Francisco, and learn on their own that hired guns are coming in to find the longshoreman and finish the theft -- which turns out to be a multimillion-dollar shipment of heroin.
