Jack Reed investigates a young woman whom he and his wife take into their household when she turns out to be targeted by unknown assassins.

When two rogues shoot at Sarah, the Police think it is the usual case of hoodlumism. But the same two men try again to kill her, killing instead a policeman. The girl is then entrusted to Jack Reed and begins to live with his family. So, while Silvera is searching for the murderers, Jack becomes convinced that Phil Brenner, former lover of Sarah, could be involved in the attempted murders.—Baldinotto da Pistoia
